WebJan 16, 2024 · Area of a circle formula If you know the radius, r, in whatever measurement units (mm, cm, m, inches, feet, and so on), use the formula \pi {r}^ {2} πr2 to find area, A: A=\pi {r}^ {2} A = πr2 The answer will be square units of the linear units, such as m {m}^ {2} mm2, c {m}^ {2} cm2, {m}^ {2} m2, square inches, square feet, and so on. WebNote that the radius is simply half the diameter. The formula for the volume of a cylinder is: V = Π x r^2 x h "Volume equals pi times radius squared times height." Now you can solve for the radius: V = Π x r^2 x h <-- Divide both sides by Π x h to get: V / (Π x h) = r^2 <-- Square root both sides to get: sqrt (V / Π x h) = r 3 comments ( 21 votes)
