Formula for finding the area of a circle = pie times the radius squared ( 3.14 x 52 )

3.14 x 25 = 78.5 (do not forget the units whether it be centimeters, inches, etc. they are squared as well. i.e. 78.5 cm2)

The area of a circle (to the nearest hundredth) with a 5-unit radius is: 78.54 square units.

78.53.14 * 5 * 5

Just like any other circle, the area of that one is (pi) times (the square of the radius).

The area of a circle with radius 5 is 25 pi. Concentric circles with radius 3 and 4 have areas of 9 pi and 16 pi. The concentric circle with radius four consumes the circle with radius 3. 25 pi minus 16 pi leaves 9 pi of the circle with radius 5 left over. 16 pi is slightly over three-fifths of the circle with radius 5.
