2 Arc LengthAn arc of a circle is a segment of the circumference of the circle.
3 Start at the point (1, 0) and walk around the circle a distance of Start at the point (1, 0) and walk around the circle a distance of radians. We will arrive at a point . The distance traveled, t, is shown in red. At the right of the circle is a red line segment that ends in a blue point that is exactly the same length as the red arc ending in the blue point. What is the distance that we walked?
4 Arc length of a circle in radians In the Unit Circle, the arc length = theta(in radians). Why?
5 Find the length of the arc formed by theta: How long is the arc subtended by an angle of radians on a circle of radius 20 cm?How long is the arc subtended by an angle of radians on a circle of radius 5 cm?Find the radian measure for the following:In a circle of radius 15 inches an angle intercepts an arc of 32 inches?
6 BonusGiven a clock with minute hand 6 cm long how far does the tip of the hand move from 12:05 to 12:20?
