Question

If the curved surface area of a hemisphere is 308 sq cm then find its volume​

Answer 1

Answer:

Given :

Curved surface area of the cone =308cm 2 and Slant height or l=14 cm.Curved surface area of the cone =πrl

308= 22/7×r×14

r= (22×14) /(308×7)

r=7cm

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

22/7 ×7)(7+14)

=22×21

Total surface area of the cone =462cm 2

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