Asubtending arc on a circle with a radius of 4.5 centimeters has an arc length of 8π. the measure of the angle subtended by the arc is__ degrees

Arc Length = (radius)(angle in radians)
             8pi = (4.5)(angle in radians)   
angle in radians = (8pi)/(4.5)
            1 radian = (180/pi) degrees
Hence (8pi)/(4.5) radians = (8pi/4.5)(180/pi) or 320 degrees

You would need a laid out graph for this but could you provide a picture of just a graph? i can give stepssolve for y.subtract 4xdivide by -1 (opposites)graph slope intercept formcheck each point to see if it’s on the graph
