Jayson wrapped plastic around a carrot shaped like a cone to create a mold for a project. The carrot had a slant height of 6 inches and a diameter of 12 inches. What is the closest to the amount of plastic he will use?

The shape formed after wrapping plastic around the carrot is a cone and the slant height is provided as 6 inches. Also the diameter is given as 12 inches, which means the radius is 6 inches (radius is half of the diameter).

The area of the plastic (which does not include the base) used shall be;


\begin{gathered} Area=\pi rl \\ \text{Area}=3.14*6*6 \\ \text{Area}=113.04in^2 \end{gathered}

This approximately 113 square inches.
