Question

Find the volume of a cylinder with radius 8cm and height 10 cm, correct to 2 decimal places.

Answer 1

`2010.62cm^3`

Explanation:

The formula for the area of a circle is :
`\pi *radius^2`

To work this out you would first have to work out the area of the circle. You can do this by multiplying pi by 8 squared, this gives you 201.06. This is because in order to calculate the volume you must calculate the area of one face of the shape.

The next step is to multiply 201.06 by 10, this gives you 2010.62.

1) Multiply pi by 8 squared.

`\pi*8^2=201.06`

2) Multiply 201.06 by 10.

`201.06*10=2010.62cm^3`
