It costs Rs. 2200 to paint the inner curved surface of a cylindrical vessel 10m deep. If the cost of painting is at the rate of `R s .20\ p e r\ m^2,` find: radius of the base inner curved surface area of the vessel capacity of the vessel

Explanation

Height of cylinder, `h=10m`

Cost of painting = Rs.20per`m^2`

`therefore` `1m^2=Rs.20`

So, C.S.A = `2200/20`

C.S.A=`110m^2`

As we know that `C.S.A = 2pirh`

`110=2xx22/7xxrxx10`

`r=1.75cm`
