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)

Part B: What is the surface area of the cone? Show your work. (6 points)

314 unit ^2

Part A

The expression that can be used to calculate surface area is

Part B

Surface area = 3.14 × 2 (2+3)

= 3.14 × 10 = 314 unit ^2

Part A : 3.14(2 × 3 + 22)

Part B: 3.14(2 × 3 + 22) 2x3=6 2x2=4 (4 + 6)= 10 3.14x10=31.4

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2
