@duglop To compute the area of a circle using the formula A = πr^2, where r is the radius of the circle, you first need to know the value of π , which is approximately 3.14159. Let's say the radius of the circle is 5 units. Plug in the values into the formula: A = π^2 A = 3.14159 * 5^2 A = 3.14159 * 25 A ≈ 78.54 Therefore, the area of the circle with a radius of 5 units is approximately 78.54 square units.
