If a circle has the dimensions given, determine its circumference.
a. 21 ft diameter
b. fraction 7 over pi
ft radius

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

- 70

this is the answer for you hope it

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,

by good luck mark me as brainliest

have a nice day
