Physical activity is important not only for losing weight, but also for keeping your bones, muscles, heart, and lungs strong. Try to do 60 minutes of moderate physical activity each day, such as jogging, walking, dancing, swimming, playing tennis, or biking.  If you’re not used to exercising, start with shorter times and less intense exercise. For example, you might start by walking for 10 minutes each day, then gradually build up to a daily 20-minute fast walk or jog. Depending on your current weight or your fitness goals, you may need to spend more time exercising or do more intense exercise. Talk to your doctor or a PE instructor to find out how much you need to exercise. In addition to aerobic activities that get your heart pumping, like running and biking, you should also do exercises that help you build muscle. At least 3 days a week, add some strengthening exercises to your regular 60 minutes of physical activity.  Some good strength-building exercises include doing planks or squats, climbing, and using resistance bands. You can also ask a fitness instructor for advice on how to safely lift weights. Building muscle helps you burn fat more efficiently, and also makes you less prone to injury. In addition to working out, you can also look for little ways to get more physical activity during your daily routines. For example, take the stairs instead of an elevator or escalator whenever you can. Every little bit can make a difference!  Doing work around your house and yard can also help you burn calories. Kill 2 birds with 1 stone by cleaning up your room or volunteering to mow the lawn. If you’re in school, try walking or biking there if possible. Even standing instead of sitting while you work at a desk can help you burn extra calories! When you have a world of entertainment and information literally at your fingertips, it’s easy to forget to get up and move. Make a decision to limit your time on the phone, at your computer or tablet, or in front of the TV.  Try setting specific limits for yourself. For example, you might commit to spending no more than 1 hour watching TV per day. If you find yourself too tempted to play on your phone, try installing an app like BreakFree or Moment that will remind you to take breaks or lock you out during designated phone-free times. If you have to sit a lot while you study or work, try to take occasional breaks to get up and walk around or stretch.

Q: These essential oils tend to naturally repel roaches. Mix 8 drops of cypress oil, 10 drops of peppermint oil, and 1 cup (240 ml) of water in a spray bottle and then spray this mixture wherever you’ve seen roaches. When in doubt, spray underneath and around your bed. Because coffee can be harmful to roaches, they tend to stay away from it. Sprinkle some coffee grounds into a few different open containers and set them under or near your bed to deter roaches. Coffee grounds can effectively repel other insects as well, such as ants, due to the caffeine they contain. The nicotine in cigars acts as a repellent for roaches. If you or someone you know smokes cigars, collect the clippings, sprinkle them in a few  containers without putting the lids on, and set them on the floor near your bed to help keep roaches away. Bay leaves also act a natural roach repellent, as roaches hate the smell of them. Use a mortar and pestle or any other crushing tools to turn some bay leaves into a powder. Sprinkle the powder in a few lidless containers and place them around your bedroom and bed. While killing roaches won’t solve the problem entirely, it will diminish the roach population in and around your home. If you’d like to kill them, mix together equal parts baking soda and sugar in a bowl. Then, simply sprinkle the mixture around your room. The sugar in the mixture will attract the roaches, while the baking soda, when consumed, will kill them.  Sweep or vacuum up the mixture after a few days and dispose of any dead roaches that you find. This mixture is safe to use with pets and children in the home. Boric acid is one of the most effective products for killing roaches, ants, and other pests. Purchase some at your local supermarket or online if you have a severe roach issue in your home. Provide a light dusting of the boric acid on the floor of your bedroom. This way, when roaches walk through it, they’ll get it on their bodies and later die when they groom themselves and ingest it.  Keep boric acid away from children and pets, as it is poisonous and can be very harmful if consumed. Don’t forget to vacuum or sweep up the boric acid after a 1-2 days. Boric acid isn’t effective when it’s wet or sprinkled in excess.
A: Spray cypress and peppermint oils under and around your bed. Repel roaches with coffee grounds. Use cigar clippings to ward off roaches. Crush up and spread around some bay leaves as an alternative. Make a homemade insecticide out of baking soda and sugar. Use Boric acid for severe circumstances.

Article: If the problem tells you the diameter of the circle, it's easy to find the radius. If you are working with an actual circle, measure the diameter by placing a ruler so its edge passes straight through the circle's center, touching the circle on both sides.  If you're not sure where the circle center is, put the ruler down across your best guess. Hold the zero mark of the ruler steady against the circle, and slowly move the other end back and forth around the circle's edge. The highest measurement you can find is the diameter. For example, you might have a circle with a diameter of 4 centimeters. A circle's radius is always half the length of its diameter.   For example, if the diameter is 4 cm, the radius equals 4 cm ÷ 2 = 2 cm. In math formulas, the radius is r and the diameter is d. You might see this step in your textbook as r=d2{\displaystyle r={\frac {d}{2}}}.
Question: What is a summary of what this article is about?
Check the problem for a diameter. Divide the diameter by two.
