Question

HELP? Aqua blue paint costs $1.50 per square inch. How much more money would it cost to paint a bowling ball with a radius 4.2913 inches in length than to paint a tennis ball with a radius 1.2598 inches in length? Round your answer to the nearest cent.
A.
$4.55
B.
$17.06
C.
$317.20
D.
$1,451.91

Answer 1

Since they are asking how much it would cost to `paint a bowling ball`, it means we will need to use the formula for surface area of a sphere to answer this.

Answer 2

Surface Area of a Sphere = \(4\pi r^2\)

Answer 3

So, to solve the problem:
1. Calculate the Surface Area of the Bowling Ball.
2. Multiply the result by 1.50 to get the amount it would cost to paint the bowling ball.
3. Calculate the Surface Area of the Tennis Ball
4. Multiply that result by 1.50 to get the amount it would cost to paint the Tennis Ball.
5. The difference between those amounts would give you your answer.
