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?
lorasvet [3.4K]
<h2>Greetings!</h2><h3>To find the total area of the bowling ball, which we presume is spherical, the equation is:</h3>

\frac{4}{3}πr³

<h3>So we know that the radius is 5, so we can substitute that into the equation:</h3>

\frac{4}{3} x π x 5³ = 523.599 or 524 to 1dp.

<h3>Seeing as this is 524 cubic inches, we can convert this into pounds by dividing this by 100, because one cubic inch weights \frac{1}{100} as stated.</h3>

524 ÷ 100 = 5.24lb

<h3>So your answer would be B, 5.24lb.</h3>
<h2>Hope this helps!</h2>
