You and your friend ordered a 12 cut pizza with a radius of 8 inches. How much cheese is needed to cover one slice of the pizza? Hint: Find the area of one slice. Round your answer to the nearest tenth
A = pi * r^2
A = 3.14 * 16
A = 50.24 square inches
50.24 / 12 = _______ square inches
4.2
Right.
To find the area of one slice of pizza, we can start by finding the area of the entire pizza and then dividing it by the number of slices.
To calculate the area of the entire pizza, we use the formula for the area of a circle: A = πr^2, where A is the area and r is the radius.
Given that the radius is 8 inches, we can substitute the value into the formula:
A = π(8)^2
Simplifying this equation, we get:
A = π * 64
A ≈ 201.1 (rounded to the nearest tenth)
Now, we can determine the area of one slice of pizza by dividing the total area by the number of slices. You mentioned that the pizza is cut into 12 slices, so:
Area of one slice = Total area / Number of slices
Area of one slice ≈ 201.1 / 12
Area of one slice ≈ 16.8 (rounded to the nearest tenth)
Therefore, one slice of pizza would require approximately 16.8 square inches of cheese to cover it.
