Question

NEED HELP:

The circumference (C) of a swimming pool is 47 feet. Which formula can you use to
find the radius (7) if you know that C = 271?

Answer 1

The radius is approx. 7.5

Let me know if it helps or if I got anything wrong!

Explanation:

To find the circumference, you need to multiply the diameter by pi (3.14)

And for vice versa, just divide.

Since we don't know the diameter nor radius, we need to divide the Circumference (C) by pi (3.14)

47/3.14=14.968

Which is rounded up to 15.

We have now found the diameter.

We also know that the radius is half of the diameter

15/2=7.5
