Step-by-step explanation:
Base radius: r = 7 m
Height: h = 11 m
The water storage tank is in the shape of the cylinder. So using the volume of cylinder formula we can find the volume of it.
V = π· r^2· h
V = π· 7^2· 11
V = 1692.46 m3 = 1692.46 kl

GivEn:
- Base radius of cylindrical water storage tank = 7m
- Depth of cylindrical water storage tank = 11 m.
To find:
- Cubic metres of water it can hold.
Solution:
• Let's consider radius of cylindrical tank be r m.
• Water it can hold = Volume.
⠀⠀━━━━━━━━━━━━━━━━━━━⠀
« Now, Finding volume of cylindrical tank in cubic metres,
→ Volume of cylinder = πr²h
→ 22/7 × (7)² × 11
→ 22/7 × 49 × 11
→ 22 × 7 × 11
→ 1694 m³
∴ Hence, 1694 cubic metres of water it can hold. ( Option - B )
⠀⠀━━━━━━━━━━━━━━━━━━━⠀
⠀⠀⠀« Additional information :
- Total Surface area of cylinder = 2πr (r + h)
- Curved surface area of cylinder = 2πrh
- Volume of cylinder = πr²h
- Cylinder is 3D shape
- Height of cylinder = v/πr²
- A Cylinder is a closed solid.
- Radius of cylinder = √v/πh
