The formula for the circumference is  \pi *d, wherein pi is 3.14, and the diameter is the whole straight of a circle. The formula for the area of the circle is  \pi  r^{2} . These are the answers for your homework.
1. Circumference = 18.84 m
    Area = 28.26
2. Circumference = 12.56 m
    Area = 12.56
3. Circumference = 62.28 m
    Area = 314 m
Thank you! Does all of it has to have m, or only some? Because some of your answers has m..
Everything needs to be. And when you are finding the area, don't forget to put the squared symbol after the measurement.
