Radians are another way ofmeasuring angles, and the measure of an angle can be converted between degrees and radians. Some key points regarding radians are – One radian is the measure of the central angle of a circle such that the length of the arc is equal to the radius of the circle....
Find the length of an arc of circle of radius 6cm subtending an angle of 15^(@) at the centre.
Find the Arc Length and the Area of a Sector of a Circle Step 1:Note the radius of the circle and whether the central angle is in radians or degrees. Step 2:Use the appropriate formula to find either the arc length or area of a sector. ...
To find the Arc Length and Sector Area of a circle, you need the formulas and in this article, we review and explain these formulas.
Arc of a circle is a portion of its circumference. Thus, the arc length of a circle is a fraction of its circumference. If θ degrees is the central angle made by an arc of a circle, then the arc length formula is θ/360 x 2πr.
