Question

In the cylindrical container, the base radius is 8 cm. If the height of the
water level is 20 cm. find the volume of the water in the container.
(a) 5.67211 (b) 4.02181 (0) 3.8925L (d) 4.971​

Answer 1

The answer is (b) 4.02181 because the volume of a cylinder is 2πrh

Given,

height=20 cm

radius=8 cm

volume of cylinder=2×22/7×8×20

                              =4.02181

Answer 2

The volume of the water in the container is 4.022857 liters.

Step-by-step explanation:

Radius of cylinder = 8 cm

Height of water level = 20 cm

Volume of water in cylindrical tank =$\pi r^2 h= \frac{22}{7} \times (8)^2 \times 20=4022.857 cm^3$

1 cubic cm =0.001 liters

4022.857 cubic cm = $0.001 \times 4022.857 = 4.022857 liters$

Hence the volume of the water in the container is 4.022857 liters.
