Radius of a circle wirh an area of 12.56mm squared is multiplied by 5 what is the area of the new circle

New area of the circle is 314 .

Step-by-step explanation:

Area of a circle is .

Let the radius of the original circle be x.

=12.56

Now, the radius is changed to 5x.

New area == 25 x .

New area= 12.56 x 25= 314

New area of the circle is 314 .

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.
