Find the arc length of the partial circle.
either enter an exact answer in terms of pi or use 3.14 for pi and enter your answer as a decimal.

9.42 Units

Step-by-step explanation:

Since the angle shown is 90 degrees we can deduce that the rest of the arc is 270 degrees therefore we can make the fraction:

270/360; 360 being the total angle measurement of a circle

270/360 simplifies to 3/4

The fraction represents how much of the circle that arc covers

Now we have to find the circumference which would be

2(3.14)r

r = 2 therefore: 2(3.14)2 = 12.56

Now that we have the circumference of the WHOLE circle we multiply it by 3/4 to find out the arc length

Which gives us  9.42

9.42

Step-by-step explanation:

12.56 is the circumference of the WHOLE circle. Now that we have that, we can find out what 3/4 is:

Therefore, the arc length of the partial circle is 9.42.
