Pat is making 5 stools with circular seats that are each 12 inches in diameter. She wants to paint the tops of all the stools bright red, but needs to know the area she will paint. What is the total area of the tops of all 5 stools?

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

- "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."
