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.

Answer 1

I hope this helps you



Volume of cone =1/3.pi.r^2.h


Volume of cone =1/3.3,14.60^2.150


Volume of cone =565.200



if 1,413cm^3 in one minute



565.200 cm^3 in ? minutes



?.1,413=565.200


?=400 minutes



1 hour =60 minutes


? hour =400 minutes


?=400/60


?=20/3 hour
