Question

If a swimming pool has a circumference of 25.12 m, what is its radius?

Answer 1

ANSWER

4 m

EXPLANATION

The circumference formula is,

$C=2\pi r$

Where r is the radius of the circle.

Solving for r,

$r=\frac{C}{2\pi}$

The circumference of the swimming pool is 25.12m. If we use 3.14 for π,

$r=\frac{25.12m}{2\cdot3.14}=\frac{25.12m}{6.28}=4m$

The radius of the swimming pool is 4 m.
