Find the total volume of the following composite figure with

h=7.5

and

r=3.6

Use 3.14 for LaTeX: \piπ.

Round to the nearest hundredth.

Given:

The height of the given fig = 7.5 unit

The radius of the given fig = 3.6 unit

To find the volume of the given composite figure.

Formula

The volume of the given fig

where,

be the volume of the cone

be the volume of the semicircle

, r be the radius and h be the height

, r be the radius

Now,

Putting, r= 3.6, h = 7.5 and π = 3.14 we get,

cube in

or, cube in

And,

cube in

or, cube in

So,

cube in

or, = 402.88 cube in

Hence,

The volume of the given figure is 402.88 cube in.

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
