I need help with this geometry question

Question

A circle with a circumference of 75.6 cm is centered at the vertex of an angle. The rays of the angle subtend an arc that is 9.66 cm long. Complete the following statements by entering numbers in the answer boxes.

A.1/360^th of the circumference of the circle is [insert answer here] cm long, so the measure of the angle in degrees is [Insert answer here]

B. The arc subtended by the angle's rays is [insert answer here] % of the circumference of the circle. Since an angle that makes a full rotation measures 360 degrees, the measure of the angle in degrees must be [Insert answer here]

Answer 1

Answer 2

You will find that 9.66/75.6=115/900=23/180=46/360.

With this information and a little arithmetic you should be able to answer all the questions fairly easily.
