The circumference of a circle is 47.1 feet. What is the diameter of the circle?

Answer :

The circunference is given by the next formula:

[tex]C=\pi\cdot d[/tex]

d is the diameter.

Then, you can solve the equation for d:

[tex]d=\frac{C}{\pi}[/tex]

Then, for the given circle:

C=47.1ft

[tex]d=\frac{47.1ft}{\pi}\approx15ft[/tex]The diameter is approximately 15ft
