You would have to add 47.50 + 122 to get 169.5 dollars. to get the amount of money he made in the summer, you would have to multiply 169.5 by 2 which would equal 339 dollars. so he made 339 dollars over the summer :)

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.
