Question

WHERE MY MATH FOLK AT?!?!

A cylindrical container, which will be used to collect oil, has a circumference of 15.5 in. and a height of 8 in.

Which estimate best approximates the amount of oil the container can hold?

Answer 1

The vol. of a cyl. is given by V = pi*r^2*h, where r is the radius and h is the height. If the circumf. of the base of the container is 15.5 in, then the radius is

15.5 in
r = ------------ = 2.468 in.
2*pi

Then the vol. of this cyl. is V = pi*r^2*h = pi * (2.468 in)^2 * (8 in). Complete the arithmetric and you'll then have your answer.
