What is the weight of a bowling ball with a 5 in. radius if we know that one cubic inch weighs 1/100th of a pound? a. 9.86 lb. b. 5.24 lb. c. 6.54 lb. d.10.99 lb.

Greetings!To find the total area of the bowling ball, which we presume is spherical, the equation is:

πr³

So we know that the radius is 5, so we can substitute that into the equation:

x π x 5³ = 523.599 or 524 to 1dp.

Seeing as this is 524 cubic inches, we can convert this into pounds by dividing this by 100, because one cubic inch weights as stated.

524 ÷ 100 = 5.24lb

So your answer would be B, 5.24lb.
Hope this helps!
