the area of sector JKL in a circle is 3pie inches squared.
Find the measure of arc JK. The radius is 6 inches.
:
The measure of the arc will the ratio of areas of sector to the circle time 360
Arc JK = %283%2Api%5E2%29%2F%28pi%2A6%5E2%29 * 360
Arc JK = %283%2Api%5E2%29%2F%28pi%2A36%29 * 360
cancel pi and 3 into 36
Arc JK = %28pi%29%2F%2812%29 * 360
12 cancels into 360
Arc JK = 30%2Api = 94.248 degrees
