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

Answer:

$576\pi$cm^2

Step-by-step 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 = $4\pi*12*12$

=$576\pi$
