Find the volume of the square pyramid shown. round to the nearest tenth if necessary.
(picture one)

a. 126 cm3
b. 907.5 cm3
c. 605 cm3
d. 55 cm3

find the surface area of the cylinder in terms of pi.
(picture 2)

a) 396 pi in^2
b) 522 pi in^2
c) 360 pi in^2
d) 1008 pi in^2

- "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."
