If you are given the radius of a circle, you can use the following formula to find the area of a circle: A = πr 2. Where: A is the area of the circle. π (pi) is a mathematical constant approximately equal to 3.14159… r is the radius of the circle. Example: Find the area of a circle with a radius of 6 units. Use 3.14 for π. A = πr 2 = (3. ...
The formula for the area of a circle is: A = πr2, where r is the radius of the circle. To find the area of a circle, follow these simple steps: find the radius of the circle (the distance from one side to the center of the circle). It is the same as half of the diameter of the circle. square the radius (multiply the radius by itself)
In order to calculate the area of a circle: Find the radius of the circle. Use the formula \text{Area of a circle} = \pi r^2 to calculate the area of the circle. Give your answer clearly with the correct units.
