Question

For exercises 1-17, be sure to label your answers. Use pi=3.14, and round your answers to the nearest tenth.
#5 find the area and circumference with radius 12 meters

Answer 1

c = 2 * r * pi
a = pi * r^2

Answer 2

c=452.2 and a=75.4 does that sound right? I plugged numbers in

Answer 3

I think you have them backwards. An area of 452.2 sounds reasonable, and so does a circumference of 75.4.
