Greetings!
To find the total area of the bowling ball, which we presume is spherical, the equation is:
[tex]\frac{4}{3}[/tex]πr³
So we know that the radius is 5, so we can substitute that into the equation:
[tex]\frac{4}{3}[/tex] 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 [tex]\frac{1}{100}[/tex] as stated.
524 ÷ 100 = 5.24lb
So your answer would be B, 5.24lb.
Hope this helps!
