Consider circle c with angle 3/4 radians. if minor arc ab measures 9n inches, what is the length of
the radius of circle c? if necessary, round your answer to
the nearest inch.
6 inches
12 inches
18 inches
24 inches

The radius of circle is 12 inches

Solution:

Given that,

Consider circle c with angle

Minor arc AB measures inches

Therefore, we can say,

To find: Radius of circle

The length of arc when angle given in radians is:

Where,

"s" is the arc length and "r" is the radius and is the central angle in radians

Thus the radius of circle is 12 inches
