Diameter of a circle formula from area
WebHow to compute the area of circle from diameter? We all know the famous area of circle formula: A = \pi r^2 A = πr2. The only "problem" is that this circle formula requires the radius. But notoriously, the radius (r) and diameter (d) are related through the formula r = \frac {d} {2} r = 2d. WebThe diameter is 0.4m, so the Area is: A = (π /4) × D 2. A = (3.14159.../4) × 0.4 2. A = 0.7854... × 0.16. A = 0.126 m 2 (to 3 decimals) And the holes are 1 m deep, so: Volume = 0.126 m 2 × 1 m = 0.126 m 3. So Max should …
