What is the volume of the sphere?
nataly862011 [7]

The volume of the sphere in the given image, to the nearest tenth, is: 2,143.6 cm³.

<h3>How to calculate the Volume of a Sphere?</h3>

A sphere is a solid shape that is round. The volume of a sphere is the amount of space it contains, which is calculated by the formula expressed as:

Volume = 4/3 × π × r³, where r is the radius of the sphere.

The parameter of the sphere is given below:

Radius of the sphere (r) = 8 cm.

π = 3.14

Substitute r = 8 into 4/3 × π × r³ to find the volume of the sphere

Volume of the sphere = 4/3 × π × r³ = 4/3 × 3.14 × 8³

Volume of the sphere = 4/3 × 3.14 × 512

Volume of the sphere = (4 × 3.14 × 512)/3

Volume of the sphere = (6,430.72)/3

Volume of the sphere = 2,143.6 cm³

In summary, the volume of the sphere in the given image, to the nearest tenth, is: 2,143.6 cm³.
