Sector Area Arc Length use different formulas. Sector Area a pr² 2p a r² 2 The same method may be used to find arc length - all you need to remember is the formula for a circles circumference. Click the Arc Length button input radius 36 then click the DEGREES button.
In general you can skip the multiplication sign so 5x is equivalent to 5x.
TH central angle C 2pr L TH C 2p L TH r You can then determine that when you multiply that equation by the central angle TH you work out the arc length formula. Arc Length Formula Arc Length radius central angle here the angle is taken in radians Consider that you have a circle with a radius of 6 meters and a central angle of 04 radians. Sector area is just a fraction of the area of the whole circle pi r2. Sector Area Arc Length use different formulas.
