Question

Three cylinders have a volume of 2826 cm. Cylinder A has a height of 900 cm. Cylinder B

has a height of 225 cm. Cylinder C has a height of 100 cm. Find the radius of each cylinder.
Use 3.14 as an approximation for T.

Answer 1

the radius of each cylinder is 1 cm, 2 cm and 3 cm respectively

Explanation:

The computation of the radius of each cylinder is shown below:

As we know that

The Volume of the cylinder = πr^2h

The radius would be

`=\sqrt{ (V)/(\pi h) }`

For cylinder A

`=\sqrt{(2826)/(3.14* 900) }`

= 1 cm

For cylinder B

`=\sqrt{(2826)/(3.14* 225) }`

= 2 cm

For cylinder C

`=\sqrt{(2826)/(3.14* 100) }`

= 3 cm

Hence, the radius of each cylinder is 1 cm, 2 cm and 3 cm respectively
