The ratio between the radius of the bawse and the height of a cylinder is 2:3, find the total surface area of the cylinder, it its volume is `1617\ c m^3`

Explanation

Given : `r/h=2x/3x`

Here, `r` = radius and `h` = height

Volume of cylinder, `V=1617cm^3`

`pir^2h=1617`

`22/7xx2x^2xx3x=1617`

`x^3=(1617xx7)/264`

`x=7/2`

So, `r=2x=2xx7/2`
