(h) An arc 14.0 cm long on the circumference of a circle subtends an angle of 128 degree. What is the radius of the circle? (e) The angle between two radii of a circle with radius 1.50 m is 0.700 rad.
WebThat is literally half of the circumference of the circle. That is half of the circumference, half of the way around of the circle, circumference of the circle. So this angle is going to be half of 360 degrees. And half of 360 is 180 degrees. And when you view it this way, these two rays share a common endpoint. WebWell, same exact logic-- the ratio between our arc length, a, and the circumference of the entire circle, 18 pi, should be the same as the ratio between our central angle that the arc subtends, so 350, over the total number of degrees in a …
WebThe circumference can be found by the formula C = πd when we know the diameter and C = 2πr when we know the radius, as we do here. Plugging our radius of 3 into the formula, we get C = 6π meters or approximately 18.8495559 m. Now we multiply that by (or its decimal equivalent 0.2) to find our arc length, which is 3.769911 meters.
