Question

Radius of s cone base and height is 14 and 24 find the surface area of a cone ​

Answer 1

Answer:

Step-by-step explanation:

Given Diameter of cone = 14 cm

Radius of cone (r) = Diameter ÷ 2 = 14 ÷ 2 = 7cm

Height of cone (h) = 24 cm

Now curved surface area of cone = πrl

where l is the slant height of cone

So to find the Curved surface area, we need to find slant height ( l )

which can be found by Pythagoras theorem

i.e.

Therefore curved surface area of cone =
