Construct a circle with center A that passes through point Z. Create four points, B, C, D, and E, spaced apart on the circle. Place them in clockwise alphabetical order at whichever locations you choose. What can you say about points B, C, D, and E with regard to the circle?

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

answer: entity is prob the answer

step-by-step explanation:

a≈380.13mi² would be your answer if the radius was 11 miles
