FINDING THE VOLUME OF A CONE

ACTIVITYLet’s make a cylinder with the same base and height. How much of the cylinder does the cone use?

V (cylinder) = πh 301.6

r=4m

SOOOO…. If the Volume of a Cylinder is 301.6, what is your guess for the Volume of the Cone with the same base and height?

How many cones do you think will fit in the cylinder?
