Anyone know the answer

The circumference of the circle is about 52.1 yards

Step-by-step explanation:

C=πd

C=2πr

C=2π(8.3)

C=16.6π

C≈16.6(3.14)

C≈52.124 yds

C≈52.1 yds

13

Step-by-step explanation:

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.
