Question

What's the circumference of a

Answer 1

Step-by-step explanation:

Radius (r) = 7 feet

circumference (c) = ?

We know

C =2 πr

= 2 * 3.14 * 7

= 43.96 feet

Hope it will help :)

Answer 2

Answer:  43.96

==================================================

Work Shown:

C = 2*pi*r

C = 2*pi*7

C = 2*7*pi

C = 14pi ............. exact circumference in terms of pi

C = 14*3.14

C = 43.96

This value is approximate because pi = 3.14 is approximate.

Note: the circumference is the same as the perimeter of the circle. It's the distance around the circle's edge.
