Question

The height of a tent is 9cm. Its base diameter is 24m.what is its slant height? Find its cost of convas cloth required 14per sq.m.?

Answer 1

Note: Tent of height 9 cm is not seem to be practical, so it is taking as 9 m.

Height, H = 9 m.
Radius, R = 24/2 = 12 m.
Slant height, L = √(H^2 + R^2) = 15 m.

Lateral surface area = π×R×L = 180π m^2
Cost = 180π × 14 = Rs. 7920/-
