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. 6.54 lb. b. 5.24 lb. c. 9.86 lb. d. 10.99 lb

The correct answer is - B. 5.24 lb.

Explanation:

Given is a bowling ball, so it is a sphere.

The radius is given as = 5 inches

Volume of the sphere =

Putting r=5 and pi = 3.142 in the above formula, we get

volume = 523.66 cubic inches

Also given is - one cubic inch weighs 1/100th of a pound

So, 523.66 cubic inches will weigh =

Hence rounding this off we get the weight of the bowling ball as 5.24 lb.
