Question

A pizza with a diameter of 18 inches is cut into 10 equal slices. to the nearest square inch what is the area of each slice of pizza

Answer 1

To find the area of each slice of the pizza, divide the total area of the pizza by the number of slices.

Step-by-step explanation:

To find the area of each slice of the pizza, we first need to find the area of the entire pizza. The formula for the area of a circle is A = πr², where r is the radius. Since the diameter of the pizza is 18 inches, the radius will be half of that, which is 9 inches. Plugging this into the formula, we get A = π(9)² = 81π square inches.

Now, since there are 10 equal slices, we can divide the total area of the pizza by 10 to find the area of each slice. Using a calculator, we can approximate π to 3.14 and divide 81π by 10 to get approximately 25.47 square inches.

Therefore, to the nearest square inch, the area of each slice of pizza is approximately 25 square inches.

Answer 2

First, find the radius.

R=d218 in2=9 inNext, find the area of the whole pie.A=π⋅r2So the area isπ⋅9 in2=81π in2Next, divide by 10 to get 8.1π in2.If you must find the approximate area it will be 8.1×π or about 25.4 square inches.
