You can put this solution on YOUR website!
volume of a right circular cylinder is pi * r^2 * h.

that would be equal to pi * 5^2 * 10 which is equal to pi * 25 * 10 which is equal to 250 * pi.

250 * pi is equal to 785.3981634 cubic inches.

none of those selections looks good.

if the selections are all * pi, then 250 * pi cubic inches would be correct.
