Question

A cone-shaped container is completely filled with liquid. The container has a radius of 60 cm and an height of 210 cm. The liquid is drained from the container at a rate of 1099 cm³ per hour. How many hours will it take to drain all of the liquid? Use 3. 14 to approximate pi. Enter your answer in the box. Hours.

Answer 1

Find the volume of the cylinder to know how much liquid is in it:

volume of a cylinder = Pi x r^2 x height.

Volume = 3.14 x 60^2 x 210

Volume = 2,373,840 cubic cm

now to find the length of time divide total cubic cm by the drainage rate:

2,373,840 / 1099 = 2,160 hours

Answer: 2,160 hours
