Volume of a cylinder is
Divide both the equation
The capacity of a small cylindrical tank is 40 litres.
A large cylindrical tank is twice as tall as the small tank
and it's diameter is three times the diameter of the small tank.
Calculate the capacity of the large tank.
Let = radius of the small tank.
Let = height of the small tank.
The volume of the small tank is: . litres.
The radius of the large tank is: .
The height of the large tank is: .
The volume of the large tank is: .
So we have: .
. . . . . . . . .
Therefore: . litres.
