The curved surface area of a cylinder is 1320 cm2 and its base had diameter 21 cm. Find the height and the volume of the cylinder.
Given data is as follows:
Curved Surface Area = 1320 cm2
We have to find the height and volume of the cylinder.
First of all, we have been given the diameter so let us find out the radius.
`r = 21/2`cm
We know that,
Curved Surface Area = `2pirh`
`2 xx 22/7 xx 21/2 xx h = 1320`
h = 20 cm
Now that we know both r and h , we can easily find out the volume.
Volume = `pi r^2 h`
=`22/7 xx 21/2 xx 21/2 xx 20`
Volume = 6930 cm3
