Height and radius of right circular cone are 8 cm and 6 cm respectively. What is its lateral surface area? Take
.
(A) 168.4
(B) 188.4
(C) 198.4
(D) 208.4
(E) None of the above
It is given to us that height of cone
cm
It is also given to us that radius of cone
cm
In
, we have
(Pythagoras theorem)
cm
Lateral surface area of cone
Hence, the answer is (B).
