To find the area of a sector of a circle, use this formula: The area of a sector \(=πr^2 (\frac{θ}{360})\), \(r\) is the radius of the circle, and \(θ\) is the central angle of the sector. To find the arc of a sector of a circle, use this formula: ...
How to Find Angles in a Circle Lesson Summary Frequently Asked Questions How can the angle of an arc be found? The angle measure of an arc is the same as the measure of the two line segments that intersect to define it. That angle is opposite the arc it creates on that circle's ci...
What is Arc Length? Thearc lengthis defined as the interspace between the two points along a section of a curve. Anarcof a circle is any part of the circumference. Theanglesubtended by an arc at any point is the angle formed between the twoline segmentsjoining the center to the end-poi...
Find the Arc Length and the Area of a Sector of a Circle Step 1:Note the radius of the circle and whether the central angle is in radians or degrees. Step 2:Use the appropriate formula to find either the arc length or area of a sector. ...
The sector of a circle is a partition of that circle. A sector extends from the center, or origin, of the circle to its circumference and encompasses the area of any given angle that also originates from the center of the circle. A sector is best thought

Alternatively, you can use a calculator or a conversion chart to find the equivalent value in radians. How do you find the arc length of a circle? The arc length of a circle can be found by multiplying the central angle (in radians) by the radius of the circle. T...
Find the area of an equilateral triangle if a side is 8\sqrt{3} m. How to make an equilateral triangle from a square An equilateral triangle is shown below. What is the value of y, the length of one side? Let \triangle ABC be an equilateral triangle inscribed in a circle and P be...
at its highest point). Place the loose end of the string at the end of the cast shadow and hold it taut. Use the protractor to measure the angle where the string meets the stick at the top. Have your partner do the same in her location at the exact same time. Record the ...
A unit circle defines right triangle relationships known as sine, cosine and tangent. These relationships describe how angles and sides of right triangles relate to one another. Say, for example, we have a right triangle with a 30-degree angle, and whose longest side, or hypotenuse, is a le...
