A student's circle calculator for the iPhone/iPod Touch and the iPad.

Calculate the circumference, diameter, radius and the area of a circle by entering any one of these inputs. This app will help beginning algebra students see the relationship of Circumference/Diameter=π


. Only one input is required to calculate the circumference, diameter, radius and area of a circle

. Field clear button

. Automatic calculation for field entry or if preferred, a manual calculate button

. Alternative value for π. Some teachers prefer a simpler value for π, such as 3.14, for classroom use. The 'value for π' setting allows for this scenario. The value for π is utilized by the app only when set to ON.

. Calculation color setting. The colors: red, green, blue or black may be set for the calculated fields to help distinguish between the user entered field and calculated fields. The user entered field is black.

. Reset settings button. The settings panel has a reset button to restore the app to the installed defaults. These defaults are: Auto Calculation = ON, Value for pi = 3.14, set to OFF, Calculation color = RED.

. More button (…) for the mathematical relationships of the circumference, diameter and radius of circles.
