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.

The Slant Height Of A Right Circular Cone Is 10 M And Its H... Curved surface area = The Slant Height Of A Right Circular Cone Is 10 M And Its H...rl = ( The Slant Height Of A Right Circular Cone Is 10 M And Its H... x 6 x 10) m2 = 60 The Slant Height Of A Right Circular Cone Is 10 M And Its H... m2.
