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?
1 answer:
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.
