Question

How do I find the interior angle and arc length/
the area of each slice of the eight sliced pizza below

Answer 1

the angle all the way round \(2\pi=360°\)


for the arc length all the way round is \(2\pi r\)

each slice is 1 eighth of the way round

Answer 2

@UnkleRhaukus , I don't get what you mean

Answer 3

the interior angle of each slice of the pizza is \(\frac{360°}{8}\)

the arc length of each slice is \(\frac{2\pi r}{8}\)

Answer 4

the area is of the whole pizza is \(\pi r^2\)
the area of each slice is \(\frac{\pi r^2}{8}\)

Answer 5

i have used some geometric facts about circles
