Step-by-step explanation:
The formula for the surface area of cone is:
Surface Area of Cone = π * r * l + π * r^2 , where l = slant height
Substituting the given values:
282.74 ft^2 = 3.14 * 5 ft * l + 3.14 * (5 ft)^2
<span>l = 13 ft</span>
A major arc is over 180°.. minor arcs are under 180°... I think this is right
Hope this helps
