Question

The curved surface area of a cylindrical road is 132 square cm and radius is 0.35 cm. Find its length

Answer 1

Correct Question,

The curved surface area of a cylindrical road is 132 cm² and radius is 0.35 cm. Find its height.

Given,

• Curved surface area of cylindrical road is 132 cm².
• Radius (r) = 0.35 cm

To Find,

• The height of a cylindrical road.

According to question,

We know that,

Curved surface area = 2πrh

⟶ 132 = 2 × 3.14 × 0.35 × h

⟶ 132 = 6.28 × 0.35 × h

⟶ 132 = 2.198 × h

⟶ h = 132/2.198

⟶ h = 60 cm

Therefore,

The height of a cylindrical road is 60 cm.

Answer 2

Step-by-step explanation:

The curved surface area of a cylindrical road is 132 cm2. Find its length if the radius is 0.35 cm. ∴ Length of road is 60 cm.
