The correct formula for the surface area of a cone is:
**πrl + πr²**
Where:
- \( r \) is the radius of the base of the cone,
- \( l \) is the slant height of the cone.
So the fourth response, **πrl + πr²**, is the correct answer.
**πrl + πr²**
Where:
- \( r \) is the radius of the base of the cone,
- \( l \) is the slant height of the cone.
So the fourth response, **πrl + πr²**, is the correct answer.
