Question

*A cylindrical pit with a depth of 5 m and a radius of 2 m was constructed. What is the volume of soil dug out?*

1️⃣ 71 cubic cm
2️⃣ 20 cubic m
3️⃣ 20 cm
4️⃣ 200 sqcm​

Answer 1

Given:

• Depth of a cylindrical pit is 5m.
• Radius of the cylinder is 2m.

⠀

To find:

• Volume of soil dug out.

⠀

Solution:

• Here, we have a cylindrical pit with depth of 5m and radius of 2m.

⠀

★ Depth of the cylinder means the height of the cylinder.

⠀

⠀⠀⠀⠀⠀♦ | Volume = πr²h | ♦

⠀

→ Volume = 22/7 × (2)² × 5

⠀

→ Volume = 22/7 × 4 × 5

⠀

→ Volume = 22/7 × 20

⠀

→ Volume = 440/7

⠀

→ Volume = 62.85

⠀

Hence,

• Volume of the soil dug out is 62.85 m³ (approx).
