Question

For each of the following angles, assume that the terminal ray of the angle opens up in the counter-clockwise direction. A circle with a radius 7 cm long is centered at Angle A's vertex, and Angle A subtends an arc length of 9.8 cm along this circle. The subtended arc is how many times as long as the circle's radius

Answer 1

9514 1404 393

Answer:

1.4

Explanation:

We want to find the multiplier n such that ...

arc length = n × radius

n = arc length / radius = (9.8 cm)/(7 cm)

n = 1.4

The subtended arc is 1.4 times as long as the circle's radius.
