how to find area of a circle

Answer 1

To find the area of a circle, you can use the formula:

Area = π * r^2

where π (pi) is a mathematical constant approximately equal to 3.14, and r represents the radius of the circle (the distance from the center of the circle to any point on its circumference).

So, if you have the radius of the circle, simply square it (multiply it by itself) and then multiply the result by π to get the area.

Answer 3

To find the circumference of a circle, you can use the formula:

Circumference = 2πr

where π (pi) is a mathematical constant approximately equal to 3.14, and r represents the radius of the circle (the distance from the center of the circle to any point on its circumference).

So, if you have the radius of the circle, simply multiply it by 2π to get the circumference.
