Dennis is entering a contest to guess the number of marbles inside a cylinder. He wants to find the volume of the marbles and the volume of the cylinder to estimate how many marbles might be in the cylinder.

Which formulas does he need to make a good guess?

Choose all answers that are correct. (In these formulas, r represents radius, h represents height, l represents length, and w represents width.)



Answer :

To find the volume of the marbles, Dennis would need the volume of a sphere.  This is [tex]4/3r^3 \pi [/tex].

To find the volume of the cylinder, he would want to know how to calculate the volume of a cylinder (Based off of radius and height).  This is [tex]r^2h \pi [/tex].
