Question

Sebuah wadah berbentuk kerucut dengan volume 16.632 cm3 dan tinggi 36 cm. Tentukan jari jari alas kerucut tersebut ​

Answer 1

21 cm

Explanation:

The computation of the radius is shown below:

As we know that

The volume of the cone =
`(1)/(3) \pi r^2h`

where

Volume of the cone is 16.632 cm^3

height = 36 cm

So, the radius of the cone is

`16.632 cm^3 = (1)/(3) * (22)/(7) * r^2 * 36\\\\16.632 cm^3 = (22)/(7) * 12 * r^2\\\\16.632 cm^3 = (264)/(7) * r^2\\\\r = √(441) \\\\r = 21 cm`
