Question

Responses

2πrl+πr2
2 pi r l plus pi r squared

πrl+πr2
pi r l plus pi r squared

2πrl+2πr2
2 pi r l plus 2 pi r squared

πrl+2πr2
pi r l plus 2 pi r squared

Answer 1

The correct formula for the surface area of a cone is:

πrl + πr²

So the correct response is:

πrl + πr² (pi r l plus pi r squared)
