A chord is a straight line that connects two points on the circumference of the circle without passing through the center. If the line passes through the center of the circle, it is a diameter. To calculate the chord length, you need to know the radius and either the central angle or th...
which is usually denoted with the Greek letter π, is the ratio of the circle's circumference to its diameter, or approximately 3.14. Pi is the fixed ratio used to calculate the circumference of the circle
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...
The examples below demonstrate how to use the PI function in Excel. # Example 1 To return the result of pi, just enter the formula below into a cell (such as D6 in this case), and then pressEnter. =PI() # Example 2 To calculate the area of a circle with the radius provided in...
How to calculate angles of a right triangle What is the height of an equilateral triangle? Given the triangle \triangle BAD with sides a = 9, \ b= 11, \ d = 5 , find the angles of this triangle. In an equilateral triangle, what is the difference between the sum of the exterior an...
How do I calculate the size of an exterior angle in regular polygons with 45 sides? How to find the number of sides of a polygon using the given angle? How do you find the measurement of the angles in a polygon? How do you prove a quadrilateral is a parallelogram...
Step 2: Calculate the linear speed of the object using the equation: v=2πrT. What is Linear Speed? Linear Speed: When an object travels in a circular motion its linear speed is the speed tangent to the circle of motion at any given point. Linear speed describes how fast th...
To calculate the other angles, we need the sine, cosine and tangent. In fact, the sine, cosine and tangent of an acute angle can be defined by the ratio between sides in a right triangle. Just like every other triangle, a right triangle has three sides. One of them is the hypothenus...
provides a relatively simple way to calculate the length of an arc. You'll need a tool called a protractor and some basic information. You must also know the diameter of the circle. Then, you can apply the following formula: length of an arc = diameter x 3.14 x the angle divided by ...
FAQ: How do you calculate the area and arc length of region ABCD using given values? What is a radian? A radian is a unit of measurement commonly used in mathematics and physics to measure angles. It is defined as the angle subtended by an arc of a circle that ha...
