RE: Math mini-contest problem for Day 9 on D.Buzz 😎

Answer

3.81% 🎯

Solution

The surface area of a 20-inch pizza is 100π square inches, or 314.16 square inches. The surface area of a 17-inch pizza is 72.25π square inches, or 226.98 square inches.

The larger pizza divided by 8 gives (314.16 square inches) / (8 slices) = 39.27 square inches per slice. The smaller pizza divided by 6 gives (226.98 square inches) / (6 slices) = 37.83 square inches per slice. Therefore, the slice of the 20-inch pizza is larger than the slice of the 17-inch pizza.

To get the percentage of how larger the bigger slice is relative to the smaller slice, we will just evaluate (39.27 / 37.83) * 100% = 3.81%.
