Question

curved surface area of a cone is 308cm2 and its slant height is 14. find a) radius of the base and b) total surface area of the cone​

Answer 1

Answer:

Step-by-step explanation:

Csa = pi*r*l

308=22/7*r*14

308*7/22*14= r

7 = r

So radius is 7 cm

Now

Tsa of cone=pi*r(r+l)

=22/7*7(7+14)

=22*21

=462cm^2
