What is the formula for calculating the curved area of a cone?
- 2/3 * pi * radius * slan height
- pi * radius * slant height
- pi * radius^2 * slant height
Explanation from PART66Online
The curved (lateral) surface area of a cone equals pi multiplied by the base radius and the slant height. Using radius squared would wrongly mix in an area term, and the 2/3 factor does not belong in the cone formula.
