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
