Question

Find the volume of the composite solid if the diameter of the cone is 18.6 inches and the diameter of the cylinder is 22.5 inches. Round your answer to the nearest hundredth. There is a cone on top of a cylinder. The height of the cylinder is 12.07, and the side or lateral height of the pyramid is 11.8. Find the volume of the composite solid if the diameter of the cone is 18.6 inches and the diameter of the cylinder is 22.5 inches. Round your answer to the nearest hundredth.

Answer 1

diameter of the cone = 18.6 inches
radius = 9.3 inches
diameter of the cylinder = 22.5 inches
radius = 11.25 inches
Volume of cone = 1/3 (pi*r^2*h)
= 1/3(3.14*86.49*11.8)
= 1068.2
Volume of cylinder = pi*r^2*h
= 3.14*126.6*12.07
= 4798.1
Total volume = 1068.2 + 4798.1
= 5866.1 inches cube
