What is the volume of the water dispenser?
(Use 𝜋 = 22/7 , Formula for the volume of a cylinder = 𝜋𝑟²ℎ)

The water dispenser is shaped like a cylinder, so the formula to find its volume is:

\[
V = \pi r^2 h
\]

Where:
- \( \pi = \frac{22}{7} \)
- \( r \) is the radius of the base of the cylinder.
- \( h \) is the height of the cylinder.

From the image:
- The diameter of the base is 42 cm, so the radius \( r = \frac{42}{2} = 21 \) cm.
- The height \( h = 40 \) cm.

Now, substituting the values into the formula:

\[
V = \frac{22}{7} \times 21^2 \times 40
\]

I'll calculate this now.The volume of the water dispenser is **55,440 cm³** (cubic centimeters).
