Answer:

B

Explanation:

Find the volume of the wading pool

Use V = pi * r^2 * h

Givens

r = 6 feet

h = 1.5 feet

pi = 3.14

2 f^2 takes 2 minutes.

Solution

V = pr * r^2 + h

r = d/2

r = 6 / 2

r = 3 feet

Put the givens into the formula

V = 3.14 * 3 * 3 * 1.5

V = 42.39 cubic feet

Time

2 cubic feet takes 1 minutes

42.39 cubic feet takes x

2/42.39 = 1/x Cross multiply

2x = 42.39 Divide by 2

2x/2 = 42.39/2

x = 21 rounded to the nearest whole number.
