Question

the height of a right cone is 12 cm and its slant height is 15 cm find the following 1.area of the base 2.volume 3.curved surface area​

Answer 1

Answer:

ANSWER

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

⇒l=

(h

)

⇒l=17 cm

Now substitute the value in above equation. we have

Curved surface area =π×8×17

⇒136π cm
