Question

C.S.A. ofa cone is 308cm and slant height is 14cm find its radius​

Answer 1

Answer:

I hope my answer help you

Answer 2

Step-by-step explanation:

Given :

Curved surface area of the cone =308cm ²

and Slant height or l=14 cm.

Curved surface area of the cone =πrl

308= 7/22×r×14

r= 7×308/22×14

r = 7cm

Total surface area of the cone =πr(r+l)

(22/7×7) ( 7+14)

22×21

Total surface area of the cone =462cm²

So, the radius of the base of the cone is 7 cm and the total surface area of the cone is 462cm ²
