To calculate the surface area of the side of a cone, we need to find the lateral area. The lateral area of a cone is given by the formula L = π × r × l, where r is the radius of the base and l is the slant height.
Given that the diameter of the base is 6 inches, the radius is half of that, so r = 6/2 = 3 inches.
The slant height is given as 4 inches.
Now we can calculate the lateral area:
L = 3.14 × 3 × 4 = 37.68 square inches.
Therefore, approximately 37.68 square inches of parchment paper is needed to cover the side of the funnel.
A cook wants to cover the side of a cone-shaped funnel with parchment paper to avoid any leaks or spills. The funnel has a diameter of 6 inches and a slant height of 4 inches. How many square inches of parchment paper is needed to cover the side of the funnel? Use 3.14 for pi and round your answer to the nearest hundredth.(
