Question

Jayson wrapped plastic around a carrot shaped like

a cone to create a mold for a project. The carrot had
a slant height of 6 inches and a diameter of 12
inches. Which is closest to the amount of plastic he
will use?
A:226 square inches
B:113 square inches
C:452 square inches
D:678 square inches

Answer 1

113.04

Explanation:

the formula for the lateral surface area of a cone (all i mean is the area up the sides and not the area of the circle on the of the cone) is the

slant height times r times pi

so put in the variables(diameter/2 = r so 12/2 = 6)

6*6*3.14 = 113.04
