HELP ASAP WILL GIVE BRAINLIEST IF CORRECT


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


Surface area = 3.14(rs + r^2)


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. (4 points)


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

Respuesta :

The expression that can be used is 3.14 (6x4+6^2)

The surface area is 188.4

Answer:

The short answer is

Step-by-step explanation:

The equation for the surface are of a cone is A= πr (r+h2+r2).  

Surface area = 3.14(rs + r^2)

Here is a screenshot because I would it explain it but you are probably just looking for an immediate answer so.
