The formula for the circumference is [tex] \pi *d[/tex], wherein pi is 3.14, and the diameter is the whole straight of a circle. The formula for the area of the circle is [tex] \pi r^{2} [/tex]. 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
