The correct formula of volume of sphere is:
[tex] V = \frac{4}{3} \pi r^3 [/tex] 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,
[tex] V=\frac{4}{3} *3.14*3.5^3 [/tex] 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!
