Question

(iv) The curved surface area of a right circular cone of height 15 cm and base
diameter 16 cm is
(A) 160 cm (B) 168
$\pi$
cm(C) 120
$\pi$
cm? (D) 136
$\pi$
cm?​

Step-by-step explanation:

The formula of curved surface area of a right circular cone =π×r×l

⇒l=

(h

2

+r

2

)

⇒l=

8

2

+15

)

⇒l=17 cm

Now substitute the value in above equation. we have

Curved surface area =π×8×17

⇒136π cm
