hope you are understand

Answer 2

Given,

The radius of a sphere (R) is 3r

To find,

The volume of a sphere

Solution,

The volume of a sphere is calculated by the formula which is given below:

The volume of a sphere = (4/3)πR^3

Putting the value of R given above in the formula:

The volume of a sphere = (4/3)×π×(3r)^3

The volume of a sphere = (4/3)× π×27r^3

The volume of a sphere = 36πr^3

Putting the value of pie(π) = 3.14

The volume of a sphere = 36×3.14×r^3

The volume of a sphere = 113.04r^3

Hence, the volume of a sphere of radius 3r is 113.04r^3
