Question: A circle has a circumference of 312in. Find the length of its diameter to the nearest integer?

 


Steven,

The relationship between the diameter (d) of a circle and its circumference (c) is

c = π d

Where π is approximately 3.14. Thus when c = 312 inches you have

312 = π d

What is d?
