What is the measure of the central angle if the arc length is 36 and the radius is 9?
It is: 36/18pi times 360 = about 229 degrees
What is the measure of the central angles if the arc length equals 3.14 and the radius equals 9?
Whoever wrote this question for you would be happy to see "pi" in the answer rather than "3.14." So I will use pi. Measure of central angle/360=arc length/2pi*r; measure.../360=pi/2pi*9; measure.../360=1/18; measure...=360/18=20. The measure of the central angle is 20 degrees.
How do you calculate the measure of a central angle of a regular nine sided polygon?
To calculate the measure of a central angle of a regular nine-sided polygon, divide 360 degrees by the number of sides. In this case, divide 360 by 9. The measure of the central angle of a regular nine-sided polygon is 40 degrees.
Circumference equals 9 and arc length is 1 what is the central angle?
arc length/circumference=central angle/360 1/9=central angle/360 central angle=40
What is the measure of a one angle of an 9gon?
If it's a regular 9 sided polygon then each interior angle will measure 140 degrees.
