Chris has a circular outdoor pen for his puppy. The distance from the center to the outside of the dog pen is 10 feet. To the nearest square foot how much space does the puppy have to run around inside the pen? A. 63 sq. ft.
B. 79 sq. ft.
C. 314 sq. ft.
D. 1,257 sq. ft.

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.
