The composite figure is made up of a cone and a half sphere. The radius of the half sphere is 6 cm. What is the volume of the composite figure? Use 3.14 for Pi. Round to the nearest hundredth. A half sphere and cylinder. Both have a radius of 6 centimeters. The cone has a height of 12 centimeters.

Recall the formulas V = one-third B h and V = four-thirds pi r cubed
188.40 cubic centimeters
489.84 cubic centimeters
904.32 cubic centimeters
1,356.48 cubic centimeters

Given:

Radius of half sphere and cone = 6 cm

Height of cone = 12 cm

To find:

The volume of composite figure that is made up of a cone and a half sphere.

Solution:

Volume of half sphere is:

Where r is the radius of the half sphere.

Putting , we get

Volume of a cone is:

Where r is the radius and h is the height of the cone.

Putting , we get

Volume of the composite figure is:

Therefore, the volume of a composite figure is 1808.64 cubic centimetres.
