The formula to find the area of a circle is A = πr^2, where A is the area and r is the radius of the circle.
Given that the diameter of the circle is 22 cm, we can find the radius by dividing the diameter by 2:
r = 22 cm / 2 = 11 cm
Therefore, the radius of the circle is 11 cm. This radius will be used in the formula A = πr^2 to find the area of the circle.

The diameter (d) of a circle is exactly twice the length of the radius (r). In other words, the relationship between the diameter and radius of a circle is given by the formula:
diameter = 2 x radius
This means that if you know the diameter of a circle, you can find the radius by dividing the diameter by 2. Conversely, if you know the radius of a circle, you can find the diameter by multiplying the radius by 2.
