Question

the curved surface area of a cylinder is 112π square meter if height of cylinder is 8m then find the cost of milk content in this vessel at the rate of rupees 45 per litre​

Answer 1

Given that curved surface area of cylinder is 264 sq cm and volume of cylinder is 924 sq m

The curved surface area of cylinder ∴πrh=264⇒h=  

2πr

264

​  

And volume of cylinder =πr  2

h=924sqm

Put the value of h

∴πr  2×  2πr

264

​  

=924⇒r=7m

Then h=  2×  722​  ×7/264

​  

=6m
