how to find area of a circle with circumference code example
Example 1: calculate area of circle
import math
r = 50
a = r**2*math.pi
print(a)
Example 2: how to find circumference of a circle
curcomfrance = pi * radius * 2
Example 3: circumference of circle
C = Pi * r * 2 (r stands for radius)
Or you could do this:
C = Pi * d (d stands for diameter)
Example 4: calculate area of circle
function calcAreaOfCircle(radius){
return Math.PI * r **2
}
function calcAreaOfCircle(diameter){
return Math.PI * (diameter / 2) **2
}
Example 5: how to find area of circle
def circle(radius):
3.14 * radius * radius
circle(12)
