Area Of A Circle Formula If you know the radius, r r, in whatever measurement units (mm, cm, m, inches, feet, and so on), use the formula π r 2 to find area, A A: A = πr2 A = π r 2 The answer will be square units of the linear units, such as
This tool will calculate the diameter of a circle from the area, and will convert different measurement units for area and diameter. Formula The formula used to calculate the circle diameter is: ø = 2 x √ (A / π) Symbols ø = Circle diameter A

A+ is all I ever see thanks to this app and it helps explain it to you as well but you do have to pay for premium to have it help you, absolutely the best app I have. Awesome app! I use it constantly to check my homework and for problems that aren't easily explained without seeing every step to get to the solution.

Always knows what sum it is and super helpful for algebra, and its really fast (maybe not the first time you use it) I would definently recommend this app if you struggle with math. And then be able to teach it to your child. BTW this is not writen by the company i am a real person.
