Question

What is the measure of the central angle of a circle with radius 5 m that intercepts a 2 m arc round your answer to the hundredths place use pie=3.14

Answer 1

22.93

Explanation:

Answer 2

the arc is like the circumference, but only a fraction of it (like the crust of a pizza slice)

ok so find what fraction of the circumference that arc is
C=2pir
r=5
c=2pi5
c=10pi

2 out of 10pi=2/10pi=1/5pi

whole circle=360
1/5pi of 360=360/5pi=72/pi=72/3.14=22.9299
round
22.93 degrees
