Question

A spherical globe has a diameter of 10 inches. What is the approximate volume of the globe?

Answer 1

523.33 in^3

Explanation:

A sphere is a 3-dimensional version of a circle. An example of a sphere is a ball

Volume of a sphere =
`(4)/(3)`π
`r^(3)`

Where

π = 3.14

r = radius

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

diameter = 2r

Radius = 10 in / 2 = 5 inches

`(4)/(3)` × 3.14 ×
`5^(3)` = 523.33
`in^(3)`
