For Question 19-20 use the figure above

A lamp shade with a circular base is an example of a solid shape called a frustrum. In the figure above, the shaded region represents a frustrum of a right cone in which the portion of the original cone that lies 12 inches below its vertex has been cut off by slicing plane (not shown) parallel to the base.
Q. What is the volume, in cubie inches, of the frustrum?

For Question 19-20 use the figure above A lamp shade with a circular base is an example of a solid shape called a frustrum. In the figure above, the shaded region represents a frustrum of a right cone in which the portion of the original cone that lies 12 inches below its vertex has been cut off by slicing plane (not shown) parallel to the base. Q. If the height and slant height of the frustrum are 8 inches and 10 inches, respectively, what is the number of inches in the radius length, R, of the original cone?

Volume of a frustrum of a cone is …….
