The circle angle will be helpful to determine the coordinates of the terminal point. This means that the shortest length from the x − x- x −, along the circle will be taken from the positive direction of x − a x i s x-axis x − a x i s. Similarly, in the second figure, the yellow line ends in the fourth quadrant of the circle. As the endpoint (where the green line ends) lies in the second quadrant of the circle, the shortest distance from the will be taken from the negative direction of x − a x i s x-axis x − a x i s. In the first figure, the line in green color is a real number t t t and t t t is the reference number associated. The shortest distance along the circle is shown in the figures. This endpoint, as already discussed, is known as terminal points. Got a question on this topic?Ī reference number is provided in terms of circle angle, which represents the endpoint on the circle.

Now, how to find the reference number? This question is answered and explained in the next section. The coordinates of the terminal points can be estimated or determined by using the reference number.

Then, the reference number t t t associated with the real number will be the shortest distance between the terminal point and the x-axis, along the unit circle that has a centre at ( 0, 0 ) (0,0) ( 0, 0 ).

The figure below shows some of the more angles.Ĭonsider a real number t t t. The angles for the circle can be represented in the form of π π π.įor example, 180 180 1 8 01 will be represented as π π π, 360 360 3 6 0 will be represented as 2 π 2π 2 π, and so on. When a circle is placed on a graphed plane, can be divided into four quadrants. One should have enough knowledge of circle angles to evaluate the terminal points.

The endpoint obtained on stopping, on the circle is the terminal point. Suppose he start from the point and walk in a counter-clockwise direction alongside the circumference of the circle till the distance t t t is covered. Let us consider that a person is going for a morning walk in a circular park having unit dimensions. Next: Write a Python program which accepts the user's first and last name and print them in reverse order with a space between them.In the morning, so many people around us going for a morning walk. Previous: Write a Python program to display the current date and time.

Have another way to solve this solution? Contribute your code (and comments) through Disqus. This code is useful to calculate the area of a circle when the radius is known, it can be used in physics and mathematical calculations or in applications that require the area of a circle to be calculated. Then it concatenates the string and the value of the radius and area using the + operator and prints the final string. The third line print ('The area of the circle with radius ' + str(r) + ' is: ' + str(pi * r**2)) uses the formula to calculate the area of the circle (pi*r**2).input() function assigns it to the variable r, it's then cast to float, so the user can input decimal number also. The second line r = float(input ('Input the radius of the circle : ')) gets the radius of the circle from the user using the input() function.It represents the ratio of a circle's circumference to its diameter (approximately equal to 3.14). The first line from math import pi imports the pi constant from the math module, which is the mathematical constant.The code uses the 'math' module's pi constant and the 'input' function to get the radius from the user, then it uses the formula to calculate the area of the circle. The said code calculates the area of a circle based on the radius entered by the user. Sample Output: Input the radius of the circle : 1.1 Print ('The area of the circle with radius ' + str(r) + ' is: ' + str(pi * r**2)) R = float(input ('Input the radius of the circle : ')) Here the Greek letter π represents a constant, approximately equal to 3.14159, which is equal to the ratio of the circumference of any circle to its diameter. In geometry, the area enclosed by a circle of radius r is πr2. Write a Python program that calculates the area of a circle based on the radius entered by the user.
