To find the surface area of a cone, you can use the formula:
Surface Area = πr(r + l)
Where r is the radius of the base of the cone and l is the slant height.
Let's calculate the surface area for each cone:
1) Surface Area = π(1)(1 + 14.9) = 204.1
2) Surface Area = π(3)(3 + 30.9) = 376.8
3) Surface Area = π(4)(4 + 28.45) = 320.3
4) Surface Area = π(0.6)(0.6 + 7.48) = 37.68
5) Surface Area = π(1.2)(1.2 + 13) = 75.36
