Question

The slant height and radius of a cone is 30 cm and 14 cm respectively . Total surface of a cone is​

Answer 1

Answer:

462 cm2

Step-by-step explanation:

Curved surface area of the cone =308cm2 and Slant height or l=14 cm.

Curved surface area of the cone =πrl

308=722×r×14

r=(22×14)(308×7)

r=7cm

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

=(722×7)(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 462cm2.
