The diameter of a circle is 20m. Find the circumference to the nearest tenth

62.8

Step-by-step explanation:

Using the circumference formula (πd) we can see that the answer is 20π, or 62.8

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.

da freeck kinda math is this just drop out
