Question

A hose dispenses 1,413 cm³ of water every minute into a cone with a radius of 60 cm and a height of 150 cm.

How long will it take to fill the cone?

Use 3.14 to approximate pi.

Enter your answer in the box.

min

Answer 1

Volume of the cone: V = 1/3 r^2 Pi * h.
V = 1/3 * 60^2 * 3.14 * 150 ;
V = 1/3 * 3600 * 471; V = 565,200 cm^3.

If 1413 cm^3 of water goes every minute into the cone, we have to divide the volume by 1413: 565,200 : 1413 = 400. Answer: It will take 400 minutes.
