Best Answer

Since the area of a circle can be represented by the equation A=πr², to find the are of a circle you merely need to fill in the variables.

The radius is half of the diameter, so a circle with a diameter of 4.4 cm has a radius of 2.2 cm. A=π(2.2)².

First, square 2.2 and you will get 4.84.

Then, multiply 4.84 by pi and you will get approximately 15.2.

The area of a circle with a diameter of 4.4 cm is approximately 15.2 square cm.
