Sign In
Use the formula for the volume of a cone.
19in.^3
The given solid is a cone and we want to calculate its volume.
Here, r is the radius and h is the height of the cone. From the diagram, we know that the radius is r= 2inches, and the slant height is l= 5inches. We are missing the value of the height.
r= 2, h= sqrt(21)
