Question

The circumference of a circle is 14 pi ft. Find its diameter, in feet

Answer 1

Answer:

The formula for area of a circle is:

A

=

π

r

2

, where

A

=

area,

π

=

22

7

, and

r

=

radius.

Since we know that the radius is half the diameter of a circle, we know that the radius of the given circle is

14
