Answer:
19 skins
Step-by-step explanation:
Total surface area of the cone = πr(r+l)
r is the radius = 10ft/2 = 5ft
l is the slant height
l^2 = 12^2 + 5^2
l^2 = 144+25
l^2 = 169
l = 13ft
Get the surface area
TSA = 3.14(5)(5+13)
TSA = 15.7*18
TSA = 282.6 ft^2
If each skin covers 15 sq. feet
Number of skin needed = 282.6 /15
Number of skin needed = 18.84
Number of skin needed is approximately 19 skins
