The slant height of a right circular cone is 10 m and its height is 8 m. Find the area of its curved surface.
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.
[A].30 m2
40 m2
60 m2
80 m2
The slant height of a right circular cone is 10 m and its height is 8 m. Find the area of its curved surface.
[A].
[B].
[C].
[D].
Answer: Option C
Explanation:
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.
