Question

the surface radius of a cone with radius r units and slant height s units is shown below part a: if r=6 units and s = 4 units write an expression that can be used to calculate the surface area of the cone.

Answer 1

Answer:

314 unit ^2

Step-by-step explanation:

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
