In order to find the answer to this problem, you want to divide 4 by 2/5. To do this, you do the following:
Put 4 over 1, so it looks like 4/1. Now, you have the equation 2/5 * 4/1. Multiply the top by the top, and the bottom by the bottom. 2 * 4 is 8, and 5 * 1 is 5. So now you have 8/5. You don't stop here, instead you need to make it a mixed fraction. To do that, you divide the bottom into top. 8 divided by 5 is 1, and you have 3 left over. You take that 3 and put it over 5 because before you divided, 5 was your denominator.

The circumference of a standard bowling ball is about 27 in. To the nearest unit, how many square inches is the surface area of

Sidana [21]

The surface area of a sphere is $S=4 \pi r^{2}$ where r is the radius;
The circumference is $2 \pi r=27 in$ so that $r= \frac{27}{2 \pi }=4.5 in$ using this value we can evaluate the surface area of 1 ball as:
$S=4 \pi r^{2} =4 \pi (4.5)^{2} =254.3 in^{2}$
For 100 ball you get: $100*254.3=25430 in^{2}$
