1 point a.
3. What is the approximate volume of a spherical ball with a diameter of 6.7 cm? Use the formula
V = say for the sphere.
141 cm
b 156 cm
564 cm
d. 1,260 cm
C
A
B.
D

step-by-step explanation:

1. the cylinder is a. 54

2.   a.108 /

1/2*qr*rs

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."
