Answer: The area of each slice of pizza can be calculated by finding the area of the whole pizza and dividing it by the number of slices.
The radius of the pizza is half of the diameter, so the radius is 20/2 = 10 inches.
The area of the whole pizza can be calculated using the formula for the area of a circle:
Area = π × radius^2
Area = π × 10^2
Area = 100π square inches
Since there are 8 slices, each slice has an area of:
100π square inches / 8 = 12.5π square inches
Therefore, the area of the 5 slices that Chris ate is:
5 × 12.5π square inches = 62.5π square inches
This is approximately equal to 196.35 square inches, when rounded to two decimal places.
