How Do You Find the Area of a Circle if You Know the Radius?
WebUsing the circumference equation x 2 + y 2 = r 2, you can choose x as a function of y, obtaining x = ± r 2 − y 2, which will be the extreme values for x. Then, you let y sweep from − r to r, which are the extreme values for y. Of course, you can alternatively do vice-versa, with y as function of x. WebApr 7, 2024 · Now, we will calculate the area of a circle by using the formula area = PI * r * r. And at last, print the area of a circle to get the output. Example: PI = 3.14 r = float (input ("Enter the radius of a circle:")) area = PI * r * r print ("Area of a circle = %.2f" %area) skyblock addons forge download
