There are two semicircles in the drawing: the arc going clockwise from a to c and the arc going counterclockwise from a to c.
AOB is adjacent to BOC
BOC is adjacent to COD
and
COD is adjacent to AOD
Since COD is 45 degrees, angle AOD is 180 degrees - 45 degrees or 135 degrees.
The circumference of the circle is pi * AC. The length of the arc AD = 135/360 * pi * AC = 1.18 * AC.
Answer:
(4,8)
Step-by-step explanation:
1=8-8 no
5=12-8 no
8=16-8 YES
10=20-8 no
0.08 divided by 1.44 is 0.055555556
<span>A
force that keeps an object at a fixed angle is called centripetal force.
Centripetal force refers to a movement of an object in a circular motion. The
velocity of an object is changing in direction but the magnitude remains. The
force of an object stays on the center; the velocity of an object depends on
the mass of an object.
One example is swinging a rope. The velocity will depends on how heavy the
object you will put on the end of the rope. The heavier the object the faster
it will rotate.</span>
