Question

A sold sphere has volume 42pie. Find the radius of the sphere

Answer 1

The Radius of sphere is 3.15 unit

Explanation:

Given as,

Volume of Sphere = 42
`\pi` unit³

From the Volume of Sphere =
`(4)/(3)`
`\pi` r³

Where r is the radius of Sphere

So , 42
`\pi` =
`(4)/(3)`
`\pi` r³

Or, 42 =
`(4)/(3)` r³

Or , r³ =
`((42 * 3)/(4))`

Or, r³ = 31.5

Or, Radius =
`\sqrt[3]{31.5}` = 3.15 unit

Hence the Radius of sphere is 3.15 unit Answer
