Abeverage manufacturer performs a taste-test and discovers that people like their fizzy beverages best when the radius of the bubbles is about .3 mm. according to the formula below, what would be the volume of one of these bubbles?

a. about 0.27 mm^3
b. about 0.11 mm^3
c. about 0.38 mm^3
d. about 0.42 mm^3

WHEN THE RADIUS IS .7mm ITS ABOUT 1.44mm^3 APEX ;)

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."
