If segment ac is 10 inches long how long is segment fa?

Segment FA will be 5 inches long because FA is a radius of the circle and AC is the diameter. To find the radius you would just cut the diameter in half.

Step-by-step explanation:

5 inches

Step-by-step explanation:

AC is the diamter, and FA is a radius,

r=1/2D so r=1/2(10)

r=5 inches

46.2+112.3

step-by-step explanation:

- "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."
