Calculate the length of the chord PQ in the circle shown below.Solution Given the central angle, C = 800 The radius of the circle, r = 28 cm Length of chord PQ =?By the formula, length of chord = 2r sine (C/2) Substitute. Length of chord = 2r sine (C/2) ...
The following are some mathematical formulae that will help you calculate the area and perimeter/circumference of a circle. Perimeter: Perimeter or the Circumference of the circle = 2 ×π× R. Length of an Arc = (Central angle made by the arc/360°) × 2 ×π× R. Area: Area of th...
Chord length of the circle=2 √ [ h (2r – h ) ] = 2r sin (θ/2). Arc Length of the circle segment=l =0.01745 x r x θ Online calculator for circle segment area calculation Area of the circular ring: Here big circle radius = R and Dia = D, ...
Radius is the length of the line segment from the center of the circle to an endpoint on the circle and diameter is twice the length of the radius of the circle. Using this definition, the formula for the diameter is D = Radius × 2....
Write down the chord length formula: c = 2 ·√(r² - d²). Here: r is the radius; c is the chord's length; and d is the chord's distance to the circle's center. Replace r and d with their respective values. The result will be the length of any chord at that distance...
Although there are many parts of a circle, the 8 main parts of a circle include the radius, diameter, circumference, arc, chord, tangent, segment, and sector. What is the Circumference of a Circle? The circumference of a circle is the total length of its boundary. In other words, if ...
