To find the area of the side of the cone-shaped funnel, we need to find the lateral area. The lateral area can be found using the formula:
Lateral area = π * r * s
where r is the radius of the base and s is the slant height.
Given that the diameter of the funnel is 6 inches, we can find the radius by dividing the diameter by 2:
radius = 6 inches / 2 = 3 inches
Substituting the values into the formula:
Lateral area = 3.14 * 3 inches * 4 inches
Lateral area = 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.
