R displaystyle r equals the length of the circles radius. You can find the frequency of the pendulum as the reciprocal of period. In other words the total distance traveled is 402 meters or a quarter mile.
Remember the circumference of a circle pi d and the diameter 2 times text radius.
L th C 2p. Th displaystyle theta equals the measurement of the arcs central angle in radians and. Remember the circumference of a circle pi d and the diameter 2 times text radius. Hence the arc length is equal to radius multiplied by the central angle in radians.
