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?

Respuesta :

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.
