A cylindrical shaped hotwater heater has a diameter of 056 m

A cylindrical shaped hot-water heater has a diameter of 0.56 m and a height of 1.17 m. If the hot-water heater is filled, determine the volume of the water in the hot-water heater in

            a) Cubic meters

            b) Liters

Solution

diameter = 0.56 m

So, radius, r = 0.28 meters

height = h = 1.17 meters

V = pi * r^2 * h

V = pi * (0.28)^2 * (1.17)

V = 0.091728pi

V = 0.288172 cubic meters approx

Now, in liters :

1 dm^3 = 1 L

So, 1 m^3 = 0.001 L

So, in liters, we get :

V = 0.288172 * 0.001 L

V = 0.000288172 liters

Answers are :

V = 0.288172 cubic meters

V = 0.000288172 liters
