suppose an arc in a circle has arc length pi/2 units and central angle 90 degrees. What is the radius of the circle?

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

answer is because 4×10=40

and 98×4= is 392

40,392
