Sum

The sum of the radius of the base and height of a solid cylinder is 37 m. If the total surface area of the solid cylinder is 1628 cm2. Find the volume of the cylinder.

#### Solution

Given data is as follows:

h + r = 37 cm

Total surface area of the cylinder = 1628 cm2

We have to find the volume of the cylinder.

It is given that,

Total surface area = 1628 cm2

That is,

2pirh + 2pir^2 = 1628

2pir ( h +r ) = 1628

But it is already given in the problem that,

h + r = 37 cm

Therefore,

2pir xx 37= 1628

2 xx 22/7 xx r xx 37= 1628

r = 7 cm

Since  h + r = 37 cm

We have,

h + 7 = 37 cm

h = 30 cm

Now that we know both height and radius of the cylinder, we can easily find the volume.

Volume = pir^2h

Volume = 22/7 xx 7xx7xx30

Volume = 4320  cm3

Hence, the volume of the given cylinder is 4620 cm3
