The top of the table is in the shape of a circle and has a diameter of 32 in. At the center of the table, there is a small circle made of marble that has a radius of 4 in. The rest of the table is made of glass. What is the area of the glass part of the table top, not including the marble Center? Use 3.14 for pi.

- "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."

what is the question?

step-by-step explanation:

x = 3 ± √(5+y)
