Question

The diameter of a basketball is 24 cm. Find its surface area. Express your answer in terms of
`\pi`.

Answer 1

Use the formula of surface area of a sphere

Answer 2

`576\pi`cm^2

Explanation:

The diameter of a basketball is 24 cm

Radius of the basket ball = diameter / 2= 24/2 = 12 cm

Surface area of the basket ball =
`4\pi r^2`

Where r is the radius of the sphere

given radius = 12cm

Surface area of the basket ball =
`4\pi*12*12`

=
`576\pi`
