Your answer gives you the central angle in radians. You now have the central angle in radians, so simply multiply the central angle by the radius to find the arc length. Thanks! We're glad this was helpful.

As we've shown above, the circle's radius is equal to the half the length of the square's side, so r=a/2. The diameter is twice the radius, so d=a. The circumference is d ·π, so C=πa. Finally, the area is π·r 2, so A= π·a 2 /4.

Web20 jul. 2024 · a → r ( t) = − r ω 2 ( t) r ^ ( t) uniform circular motion . Because the speed v = r ω is constant, the amount of time that the object takes to complete one circular orbit of radius r is also constant. This time interval, T , is called the period. In one period the object travels a distance s = vT equal to the circumference, s = 2 π r; thus
