Question

A slice is cut from a circular pizza with a diameterHey of 18 inches. The arc length, or curved edge of the pizza, that was cut measures 6.5 inches. What is the measure of the central angle that was used when cutting the pizza, in radians to the nearest tenth

Answer 1

(6.5 / 18π) (2π) = ?

Answer 2

Use the relation between arc length, A, radius of circle, r , and theta, the angle measure

A = r* theta

theta = A/r

given diameter = 18, r= 18/2=9

arc length A= 6.5

plug in the values, you should get angle measure in radians.

hope this helps!
