![]() ![]() Radius from Chord- This computes the radius of a circle based on the length of a cord and the cord's center height.Radius from Area - This computes the radius of a circle given the area.Circumference from Area - This computes the circumference of a circle given the area.Radius from Circumference - This computes the radius of a circle given the circumference.Circle around a Triangle - This computes the radius of a circle that circumscribes a triangle given the length of the three sides ( a,b,c) of the triangle.Circle within a Triangle - This computes the radius of a circle inscribed within a triangle given the length of the three sides ( a,b,c) of the triangle.Arc Lengths - This computes the length of an arc of segment on a circle given the radius (r) and angle ( Θ).Circumference - This computes the circumference of a circle given the radius ( C = 2 π r).Radius - Center to a Point - This computes the radius of a circle given the center point ( h,k) and any other point ( x,y) on the circle.Area of Annulus- This computes the area of an annulus (ring) given the inner radius ( r) and outer radius ( R).Sector Area f(r,Θ)- This computes the area of a sector (pie slice) of a circle given the radius ( r) and angle ( Θ).Segment Area f(r,h) - This computes the area of an arc segment of a circle given radius ( r) and the depth ( h) into the circle.Segment Area f(r,θ) - This computes the area of an arc segment of a circle given the radius ( r) and angle ( θ).Circle Area - This computes the area of a circle given the radius (A = π r 2).The formula for the arch length from the length of a chord and radiusis: However, this can be automatically converted to other length units via the pull-down menu. INSTRUCTIONS: Choose units and enter the following:Īrc Length of a Circle (a): The calculator compute the length in meters. Now, length of a common chord of two circles 2R1 × R2 / Distance between the two centers of the circle >2 × 5 × 6/8 > 60/8 > 7. The radius of the two circles is R1 and R2 with lengths 6cm and 5cm respectively. The Arc Length a Circle from the Chord and Radius calculator computes arc length of a circle based on the length of a chord ( d) on a circle and the radius ( r). The distance between the two centers is 8cm. ![]()
