If the diameter is 9 cm the radius is 4.5 cm (half the diameter). The area of a circle is given by the formula: 4πr^2, where π is the constant ratio of circumference to diameter (3.14159...).

3.14 cm x 4.5 cm = 14.13 cm^2. Remember, the units must be squared to represent area. 14.13 is extended to the nearest hundredth.

Volume of a cylinder:

The volume of a cylinder with radius r and height h is given by:

$V = \pi r^2h$

A cylinder has a height of 12 inches and a radius of 1.5 inches.

This means that $h = 12, r = 1.5$

What is its volume?

$V = \pi r^2h = 3.14(1.5)^2(12) = 84.78$

It's volume is of 84.78 cubic inches.
