How many inches is each slice of pizza?

Hey!

First, let's find the area. The formula for finding area of a circle is: π · r²

Radius is ½ of the diameter. Divide the diameter by 2 to get the radius.

d = 18

18 ÷ 2 = 9

r = 9

r² = 9 × 9 = 81

The area of the whole pizza is 81π. There are 10 slices. Divide the area of the whole pizza by 10 to find the area of 1 slice.

81π ÷ 10 = 8.1π

That means each slice is 8.1π inches²

im alright what do you need

step-by-step explanation:

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
