The formula to find the area of a circle is A = πr^2, where r is the radius of the circle.
Given that the diameter of the circle is 22 cm, we know that the diameter is twice the length of the radius. Therefore, the radius (r) is half of the diameter.
r = 22 cm / 2 = 11 cm
So, the value of the radius we will use in the formula to find the area of the circle is 11 cm.
A circle has a diameter of 22 cm. Derive the value of the radius that you will use in the formula to find the area of the circle.
