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

Answer:

The volume of the candle is $147\ in^{3}$

Step-by-step 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

$\pi=3.14$

$V=46.875(3.14)=147\ in^{3}$
