Question

A manufacturer makes candles in the shape of right circular cylinders and right circular cones. Part A) One candle, in the shape of a cylinder, has a height of 7.5 inches and a diameter of 5 inches. What is the volume of the candle? round all answers to the nearest inch

Answer 1

The volume of the candle is
`147\ in^(3)`

Explanation:

we know that

The volume of a cylinder (candle) is equal to

`V=\pi r^(2) h`

we have

`r=5/2=2.5\ in` ----> the radius is half the diameter

`h=7.5\ in`

substitute

`V=\pi (2.5)^(2) (7.5)`

`V=46.875\p\ in^(3)`

assume

`\pi=3.14`

`V=46.875(3.14)=147\ in^(3)`
