What is the approximate radius of a sphere with a volume of 1436cm to power of 3

Step-by-step explanation:

Volume of a sphere is given by

where r is the radius

From the question V = 1436 cm³

Multiply through by 3

We have

Divide both sides by 4π

Find the cube root of both sides

r = 6.99

We have the final answer as

Hope this helps

- "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."
