Question

find the curved surface area and total surface area of a cone with diagram​

Answer 1

total surface area= curved surface area+ area of base.

Answer 2

Answer:

Curved Surface Area of Cone :

$\pi.r.l$

To find CSA of cone first multiply the radius of the cone by pi. Again multiply the answer with the length of the cone to get a required answer.

Total Surface Area of Cone:

$\pi.r(l + r)$

To find TSA of cone add on the area of the base of cone
