The radius of a sphere is 12 units. Find the volume of the sphere. Write your answer in terms of pi.

V = 2304π units³

Step-by-step explanation:

The volume (V) of a sphere is calculated as

V = πr³ ( where r is the radius ) , then

V = π × 12³

   = π × 1728

   = 4π × 576

   = 2304π units³

- "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."
