The distance around a circular pool is 39.25 m. How does the lifeguard have to walk from the edge of the pool to the centre of t
Marysya12 [62]

Answer:

d = 6.246 m

Step-by-step explanation:

Given that,

The distance around a circular pool is 39.25 m.

We need to find how does the lifeguard have to walk from the edge of the pool to the centre of the pool. It means we need to find the radius r of the circle.

ATQ,

Circumference = 2πr = 39.25 m

r is radius

r=\dfrac{39.25 }{2\pi}\\\\r=6.246\ m

So, the required distance is 6.246 m.
