The circumference (C) of a swimming pool is 47 feet. Which formula can you use to find the radius (r) if you know that C = 2πr ?

To find the radius (r) from the circumference (C) of a swimming pool, you can rearrange the formula (C = 2pi r).

To isolate r, you divide both sides by (2pi):

[

r = frac{C}{2pi}

]

Thus, the correct answer is:

r = C/2π

This formula allows you to calculate the radius when you know the circumference. If you have any more questions or need further assistance, feel free to ask!
