To determine the amount of whipped cream needed to go around the edge of a pie, you would need to calculate the circumference of the pie. The circumference refers to the distance around the circular edge of the pie.
The reason you would use circumference and not area in this case is because the whipped cream is going along the edge, which is a one-dimensional line. If you were covering the entire top surface of the pie with whipped cream, you would then need to calculate the area, as area measures the two-dimensional space that is covered.
To calculate the circumference of a pie, you use the formula:
Circumference (C) = 2 * π * r
where "r" is the radius of the pie (the distance from the center of the pie to the edge). If you know the diameter (the distance across the pie, passing through the center), the formula is:
Circumference (C) = π * d
where "d" is the diameter of the pie.
You can then use this measurement to gauge how much whipped cream you need based on the thickness you want to apply around the pie's edge.
for each quantity, decide whether circumference or area would be needed to calculate it. Explain or show your reasoning
