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 hundredth
To find the area of the side of the cone-shaped funnel, we need to calculate the curved surface area (CSA) of the cone.
The formula for CSA of a cone is given by: CSA = πrℓ, where r is the radius of the base and ℓ is the slant height.
Given that the diameter of the base is 6 inches, we can calculate the radius by dividing it by 2: r = 6/2 = 3 inches.
So, the CSA of the cone is: CSA = π * 3 * 4 = 12π square inches.
Now substituting the value of π as 3.14, we get: 12π = 12 * 3.14 = 37.68 square inches.
Therefore, approximately 37.68 square inches of parchment paper is needed to cover the side of the cone-shaped funnel.
