To find the length of the arc in a circle with a diameter of 8 feet, if the central angle determining it measures 330 degrees, first you need to change the 330 degrees to radians:You need the radius, not the diameter. Half of 8 is 4 , the radius. Now, use that in the formula ...

Arc length formula with degrees: Using the radian formula was faster, since the angle was in radians. 2. Find the arc length in a circle of radius 12 cm with a central angle of 1.2 radians.3. Find the length of the minor arc from point A to point B, when the radius of the circ...
Sector of a Circle:The sector of a circle is defined as the area enclosed by two radii and the corresponding arc in a circle. There are two types of sectors, minor sector, and major sector. What are radians? Radians are another way ofmeasuring angles, and the measure of an angle can ...
