Question

The diameter of a sphere is 6ft 6in. Find the radius

Answer 1

3ft 3 in

Explane:

1/2 diameter = radius

Answer 2

The diameter of a sphere is 6ft 6in. The radius of sphere is 3 feet 3 inches.

Solution:

Given that the diameter of sphere is 6 feet 6 inches.

We have to find the radius of the sphere.

The relation between diameter and radius of sphere is given as

`\text { diameter }=2 * \text {radius}`

Therefore,
`radius=\frac{\text {diameter}}{2}`

`radius=\frac{6 \text { feet } 6 \text { inches }}{2}`

Radius = 3 feet 3 inches.

Hence the radius of the sphere is 3 feet 3 inches.
