Question

John is ordering a pizza for his graduation party. He wants each slice to be cut at an angle of 36°
so that each person has 10π
square inches of pizza. How long should the radius of the pizza be?(1 point)

50 in.

1 in.

10 in.

20 in.

Answer 1

Sector area = (θ/360)·πr^2 = (36/360)·πr^2 = (1/10)πr^2.
Set (1/10)πr^2 = 10π → r^2 = 100 → r = 10 in.

Answer: 10 in.
