Question

A circle of radius 5, for an angle x, has an arc length of 3 $pi$ . What is angle x?

144 degrees
108 degrees
43.5 degrees
96 degrees

hint Hint:

Arc length = ( $fraction numerator m e a s u r e blank o f blank a r c over denominator 360 blank d e g r e e s end fraction$ )×circumference

The correct answer is: 108 degrees

Arc length = ( $fraction numerator m e a s u r e blank o f blank a r c over denominator 360 blank d e g r e e s end fraction$ )×circumference
Let measure of arc be c.
2 $pi$ =360 degrees ; $pi$ =180 degrees
3 $pi$ =( $fraction numerator x over denominator 2 pi end fraction$ )×2× $pi$ ×5
x= $fraction numerator 3 pi over denominator 5 end fraction$ =108 degrees
