Question

A cylindrical water storage tank has an inside base radius of 7 m and depth of 11m. How many cubic meters of water can it hold?

a). 3388 m3

b). 1694m3

c) 847 m3

d). 484 m3​

Answer 1

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

Answer 2

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
