Question

the radius of the base and the height of a cylinder are in the ratio 2 is to 3 if its volume is 1617 cm cube find the total surface area of the cylinder
​

Answer 1

Answer:

For the cylinder,

Let the radius be 2x

Let the height be 3x

Given,

Volume=1617

πr²h=1617

22/7*(2x)²*3x=1617

4x²*3x=1617*7/22

4x²*3x=514.5

4x²*3x-514.5=0
