A city's water tower is built using a right circular cone and a right cylinder, as shown. About how many cubic feet of water can this tower hold, when completely full? What is the volume and surface area of the cylinder made from this net?

A. 89,019 cubic feet
B. 953,775 cubic feet
C. 6358.5 cubic feet
D. 2,142,000 cubic feet

- "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: 0,6

step-by-step explanation:

this would make it the y intercept.
