The radius of circle A is half of the radius of circle B. What is the area of circle A A) 1/2 the area of circle B
B) 1/4 the area of circle of B
C) pi/4 the area of circle of B
D)pi/2 the area of circle B
E) square root of 1/pi the area of circle B

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.

step-by-step explanation:

i think you should think about the question and not look online.
