Question 81

Curved surface area of a cylinder is 1232 sq cm. If circumference of its base is 154 cm, then what will be the height of the cylinder? (Take π = 22/7)

Solution

Let radius of base of cylinder = $$r$$ cm and height = $$h$$ cm

Circumference of base = $$2 \pi r = 154$$

Curved surface area of cylinder = $$2 \pi r h = 1232$$

=> $$154 \times h = 1232$$

=> $$h = \frac{1232}{154} = 8$$ cm

=> Ans - (C)
