The curved surface area of a right circular cone of height 15 cm and base diameter 16 cm is __________.
ANSWER
The formula of curved surface area of a right circular cone =π×r×l
⇒l=
(h
2
+r
2
)
⇒l=
8
2
+15
2
)
⇒l=17 cm
Now substitute the value in above equation. we have
Curved surface area =π×8×17
⇒136π cm
