The formula for circumference is:
C = πd
where C is the circumference, π is pi (approximately 3.14), and d is the diameter.
We can rearrange this formula to solve for d:
d = C/π
Plugging in the given values, we get:
d = 47.1/3.14
d ≈ 15
So the circle's diameter is approximately 15 inches.
A circle has a circumference of 47.1 in. What is the circle's diameter?
(Use 3.14 for pi)
