Answer 2

Answer:

TSA of cone=462$cm^{2}$

Step-by-step explanation:

Solution:-

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

Curved surface area of the cone = πrl

308 = 22/7*r*14

r= (308*7)/(22*14)

r = 7 cm

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

= (22/7*7)(7+14)

= 22*21

Total surface area of the cone = 462 sq cm

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