The height of a cone is 20m and its baseradius is 50cm - Find the curned surfacearea and the total surface areaof the cone.​

Answer»

Answer:

GIVEN height= 20cm ,

BASE radius = 50cm ,

To FIND: CSA of cone and TSA of cone

Solve : CSA of cone = πrl

= 22\7 x 50 x 20

3142.8..CM2

and TSA of cone = πr(l+r)

= 22\7 x 50 ( 20+50 )

= 22\7 x 50 ( 70)

= 1100cm2

this is the final answer.!
