If the area of a sector is known, and the angle (θ) subtended by the arc is known, the radius can be calculated by substituting the given values in the formula, Area of a Sector of a Circle = (θ/360º) ×πr2. For example, let us find the radius if the area of a sector...
Step 1 –In the “ Enter information “ section of the circle area calculator, we will have to select “ area “ as that is what we are required to find. Below is a snapshot of what the drop options would look like – Step 2 –Once we have selected the area as the option, we w...
The segment of the circle formed by these two radii is referred to as the sector. What is the formula for the area of a sector of a circle? The formula for the area of a sector of a circle is: A=(n/360)*3.14r^2 In this formula, n represents the measure of the central ...
Area of Segment of a Circle The basic formula for the area of a circle, area \( = \pi {r^2}\) can be applied to find the area of both the minor and the major segments of the circle. If \(r\) be the radius of a circle and \(\theta \) (pronounced ‘theta’) be the angl...
Circle area formula in terms of circumference A =C24π See below some definitions related to the formulas: Circumference Circumference is the linear distance around the circle edge. Radius Theradiusof a circle is any of the line segments from its center to its perimeter. The radius ...
Area of Sector = θ × π360× r2 (when θ is in degrees)Area of SegmentThe Area of a Segment is the area of a sector minus the triangular piece shaded blue below:There is a lengthy reason, but the result is a slight modification of the Sector formula:...
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. ...
Sector & Segment A sector is a part of a circle surrounded by two radii of it together with their intercepted arc. The segment is that region which is enclosed by a chord together with the arc subtended by the chord. You can download Perimeter and Area Cheat Sheet by clicking on the dow...
Radius of Curvature Formula Segment of a Circle Sector of a Circle Radius of Circle Examples Example 1:Find the radius of the circle whose center is O (2, 1), and the point P (5, 5) lies on the circumference. Solution: The radius of circle equation in the cartesian plane is given ...
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. ...
