Question

Find the circumference and the area of a circle with diameter 4 ft.

Answer 1

Answer:

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 ;)
