7 foot circumference X 12 inches/foot = 84 inches in circumference
Circumference of the circle = 7*pi feet
The circumference is about 22 units.
Circumference = pi x r squared: where pi = 3.14159 and r = radius (squared) Circumference = 3.14159 x 7 x 7= 153.938 feet
When you are given the circumference of a circle asked to find the diameter, divide the circumference by pi. The formula for circumference is pi x diameter, so the formula for diameter is circumference divided by pi. So 7 divided by pi equals about 2.22.
