In a circle with a radius R, since the arc length of the 360° center angle is equal to the circumference length \(C=2πR\), the arc length of the n° center angle is \(l=( n°πR)/180°\) In the arc system, if the central angle of the arc is θ, then there is a for...
How to Calculate the Area of a Circle You can find the area of a circle using acalculator, or you can use the circle area formula: A = πr² The areaAis equal to pi times the radiusrsquared. How to Find the Circumference

1). What is the angular speed of rotation (in revolutions per mins) of the wheels of the car that's moving with speed 72km/hr if the diameter of its wheel is 64cm? 2). A jet is flying in a circle of radius 7km around a camera. It c...
Answer to: Solve cos \ x= \frac {-1}{2} in radius without the use of a calculator or unit circle By signing up, you'll get thousands of...
Compute the circumference of the Earth using the distance and angle measurements you have. Since the locations are points on a circle that goes around the Earth, the distance between them can be expressed as an arc measurement on a 360-degree circle. For Eratosthenes, the arc was 7.2 degrees...
Square inches of a circle calculator. FAQs What is the radius of a unit circle? By definition, a unit circle is a circle with a radius of 1. It is a general object used in mathematics (e.g., when explaining trigonometric functions), so the 1 usually has no unit assigned. What is ...
