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 = [tex]\frac{4}{3} \pi r^{3}[/tex]
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 = [tex]\frac{523.66}{100}=5.2366[/tex]
Hence rounding this off we get the weight of the bowling ball as 5.24 lb.
