Question

Carlos wants to build a circular hot tub with a volume of 1,000 ft3. What is a good approximation for the radius of the tub?

Answer 1

Answer:

6.2 feet

Step-by-step explanation:

we can determine the radius from the volume of the hot tub

volume of a sphere = (4/3) x (n) x (r^3)

n = 22/7

r = radius

1000 = (4/3) x (22/7) x r^3

divide both sides of the equation by  (4/3) x (22/7)

238.636 = r^3

find the cube root of both sides

r = 6.20 feet
