Question

The slant height of a right circular cone is 10 m and its height is 8 m. Find the area of its curved surface.

Options:

A . 30

m²

B . 40

m²

C . 60

m²

D . 80

m²

Answer: Option C

l = 10 m,

h = 8 m.

So, r = l² - h² = (10)² - 8² = 6 m.

Curved surface area = rl = ( x 6 x 10) m² = 60 m².
