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>
I believe you use division. the question states he bought some boxwood for $12 each, and had a total of $432. you divide 432 by 12 to find the exact amount of how many boxwood were purchased.
The answer should be 36
