Question

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 = 3 units and s = 5 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)

Answer 1

Answer:

Step-by-step explanation:

The way to find the surface area is

$\pi r(l+r)$

and the surface area

3.14 × 2 (2+3) = 3.14 × 10 = 314 unit ^2
