Question

Find the surface area of a ping-pong ball if the diameter of the ping pong ball is 1.4882 inches round your answer to the nearest hundredth

Answer 1

`SA=6.96\ in^2`

Explanation:

Surface Area

Given a sphere of radius r, the formula to compute its surface area is

`SA=4\pi r^2`

The ping-pong ball (assumed as a sphere) has a diameter

`d=1.4882\ inches`

Since the diameter is twice the radius, then

`r=d/2=1.4882\ inches/2=0.7441\ inches`

Thus, the surface area is

`SA=4\pi\cdot 0.7441^2`

`\boxed{SA=6.96\ in^2}`
