Hey there!!

How do we find the volume of a sphere?

Ans : We use the formula 4/3 ( πr³ )

Diameter given - 18 inches

Diameter - 2 × radius

Let's take the radius as x

2x = 18

Divide by 2 on both sides

... x = 9

Hence, the radius of the sphere is 9 in.

Now substitute these values in the formula given.

... ( 4 / 3 ) ( 3.14 × ( 9 )³ )

... ( 4 / 3 ) ( 3.14 × 729 )

... ( 4 / 3 ) ( 2289.06 )

... ( 4 ) ( 763.02 )

... 3052.08 in³

Hence, the required answer is 3052.08 in³.

Hope my answer helps!!
