Question

I need to know the circumference to this and area of this circle

Answer 1

C = 21.98 ft^2

A = 38.465 ft^2

Explanation:

The diameter is 7 ft

The radius is 1/2 of the diameter so 1/2 *7 = 3.5 ft

Circumference = pi*d

C =pi* 7

C =3.14 *7

= 21.98 ft^2

A = pi*r^2

= 3.14 (3.5)^2

= 3.14 (12.25)

= 38.465 ft^2
