Question

What is the measure in radians for the central angle of a circle whose radius is 9 cm and intercepted arc length is 7.2 cm?

? Radians

Answer 1

The correct answer is 0.8 radians.

Explanation:

Verified by correct test results.

Answer 2

arc length = radius * central angle (in radians)
central angle (in radians) = arc length / radius
central angle (in radians) = 7.2 / 9
=.8 radians
