To find the area and circumference of a circle, you can use the following formulas:
1. Area of a circle (A): A = πr², where π (pi) is approximately 3.14159 and r is the radius of the circle.
To find the area of a circle, square the radius and multiply it by π.
2. Circumference of a circle (C): C = 2πr, where r is the radius of the circle.
To find the circumference of a circle, multiply the radius by 2π.
You can use these formulas to calculate the area and circumference of any circle.
