Question

V = 4/3r3. A sphere has a radius of 3.5 inches. Volume (to the nearest tenth) =

Answer 1

The correct formula of volume of sphere is:

`V = (4)/(3) \pi r^3` Where r is the radius of sphere.

Given, r = 3.5 inches.

So, first step is to plug in r = 3.5 in the above formula to get the volume: V. Hence,

`V=(4)/(3) *3.14*3.5^3` Since, π = 3.14

= 1.33333 * 3.14 * 42.875

= 179.5028846

= 179.5 Rounded to nearest tenth.

So, volume of sphere is 179.5 cubic inches .

Hope this helps you!
