For a circle, the arc length formula is θ times the radius of a circle. The formulas are:Arc Length = θ× r (used for radians) Arc Length = θ× (π/180) × r (used for degrees)Where,L = Length of an Arc θ = Central angle of Arc r = Radius of the circle...
Length of Chord Formula:It can be calculated if the angle made by the chord at the center and the value of the radius is known. Length of chord = 2 r sin(θ/2). Here, θ is in radians. Area of Segment Formula:The segment of a circle is the region formed by the chord and the ...
formula needs a couple of constant values. These are injected into the query using withSideEffect steps. The first constant, rdeg represents one degree in radians. This is the result from dividing PI by 180. The second constant gcmiles represents the average radius of the Earth in miles. Th...
So, what is the area formula for a rectangle, a triangle and a circle? Learn how to calculate the area for each using the area formulas in the examples below. How to Calculate the Area of a Rectangle Need to know what size rug to buy? Calculate the area of your rectangular space ...
In summary, the formula to find the area of a sector in a circle is A = (πr^2θ)/360, where θ is the central angle in degrees. If θ is in radians, the formula becomes A = (r^2θ)/2. The sector area is simply a fraction of the total area of the circle. ...
There is a lengthy reason, but the result is a slight modification of the Sector formula:Area of Segment = θ − sin(θ)2× r2 (when θ is in radians)Area of Segment = ( θ × π360 − sin(θ)2)× r2 (when θ is in degrees)...
