The volume of a cylinder with a radius of 3 cm and a height of 8 cm is: 226.19 cm3
1.8 cm The radius is half of the diameter.
volume of a cylinder = Pi * radius * radius * height = 22/7 * 3 * 3 * 8 = 226.286 {| |}
The area of a circle is pi times radius times radius. 6 cm = 2 times 3 cm radius = 3 cm. SO, pi times 3 cm times 3 cm 9 pi pi is approximately 3.141592... 9 times 3.141592... is 28.274328...
