Question

The figure is made up of a cylinder and a half sphere. What is the volume of the composite figure? Use 3.14 for Pi. Round to the nearest hundredth.

A cylinder and half sphere. Both have a radius of 4 millimeters. The cylinder has a height of 7 millimeters.

Recall the formulas V = B h and V = four-thirds pi r cubed

Answer 1

351.68 millimeters for the cylinder and 8 23/75 millimeters for the half circle.

Explanation:

Volume Cylinder = 3.14(16)(7) = 351.68

Volume Half sphere = 2/3(3.14)(4) = 8 23/75

If you want both of them together just add up the two numbers.
