Answer 1

I hope this helps you

Answer 2

Answer: The radius is 3 inches.

Explanation:

Formula : Volume of sphere =
`(4)/(3)\pi r^3`, here r= radius of the sphere.

Given, the volume of a spherical ball is 113.04 cubic inches.

`\Rightarrow(4)/(3)\pi r^3=113.04\\\\\Rightarrow r^3=(113.04*3)/(4\pi)`

Substitute ,
`\pi=(22)/(7)`

`\Rightarrow\ r^3=(113.04*3)/(4*(22)/(7))\\\\\Rightarrow\ r^3=(113.04*3*7)/(4*22)\\\\\Rightarrow\ r^3=26.9754545455\approx27\\\\\Rightarrow\ r=3\text{ inches}`

Hence, the radius is 3 inches.
