given,

radius of sphere , r = 8cm
We know that,
Volume of sphere = 4/3 pi r^3 cubic units

=> Volume of sphere , V = 4/3 x 3.14 x 8 x 8 x 8

=> Volume of sphere , V = 2143.573 units

Rounding of to nearest tenth , V =2143.58 units

Given:

  • Radius= 8 centimeters

To find:

The volume of the given sphere.

Solution:


\large\boxed{Formula:V = (4)/(3) \pi {r}^(3)}


\large\boxed{\red \pi \red = \red 3 \red . \red 1 \red 4}

Let's solve

Substitute the values according to the formula.


V = (4)/(3) * 3.14 * {8}^(3)


V = 2143.573333 \: {cm}^(3)


\large\boxed{= 2143.6 \: {cm}^(3) \: (nearest \: tenth)}

Hence, the volume of the given sphere is 2143.6 cubic centimeters.
