The total surface area of cone is 942 cm².
What is Total surface area of Cone?
Total surface area is the sum of the area of the circular base and the area of the curved part of the cone.
The total surface area of a cone is the sum of the area of the base and the lateral area:
SA = πr² + πrl
where, r is radius
l is slant height
Now, for finding the slant height of the given cone is
l² = r² + h²
l² = 12² + 5²
l² = 144 + 25
l² = 169
l = 13 cm
Now, SA = π X 12² + π X 12 X 13
= 144π + 156π
= 300π
= 300 X 3.14
= 942 cm²
Thus, the total surface area of cone is 942 cm².
