Find the circumference and the area of a circle with diameter 4 ft.
use the value 3.14 for pie, and do not round your answers. be sure to include the correct units in your answers.
circumference:
area:

To find the circumference of a circle, your equation is 2*pi*radius

C=2*3.14*2 (radius is half of diameter so 4/2=2, 2=radius)

C=12.56 ft

To find the area of a circle, your equation would be pie*r^2

A=3.14*2^2

A=3.14*4

A=12.56 sq. ft

Hope this helps ;)

understand that i don't know the answers

will someone answer his question
