If the radius of a circle is given as “r” and the angle of the sector is given as . This angle is made by the two radii at the center. As we know, for a complete circle, the angle made at the center is equal to 2 or $360^\circ$. ... chords. diameters. radii. tangents. Correct Incorrect. Correct ...
WebSep 12, 2014 · If you draw a perpendicular to the chord through the radius point, you will have formed two right triangles, and split the delta in half. The angle between the radius and chord is then 90 - delta/2 I would note that your delta seems to be in packed format and should be read as 26d 33' 29". WebStep 3: Arc length = radius × central angle = 2 × 12.5 = 25 units; Thus, arc length = 25 units. Radius and chord length: Substitute the values of radius and chord length in the formula of chord length. Then solve for the central angle. Calculate the arc length.
