Answer:
Step-by-step explanation:
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.
