The surface area of a cone with radius r units and slant height s units is shown below:

Surface area = 3.14(rs + r2)

Part A: If r = 2 units and s = 3 units, write an expression that can be used to calculate the surface area of the cone. (4 points)

Answer 1

np

Explanation:

3.14(rs + r2)

3.14 (r= 2 x s= 3 + r =2 x 2)

3.14 ( 6+4)

3.14 (10)

3.14 x 10 = 31.4 units ² I guess
