4 dni temu · So you might be confused as to how to find the volume of a rectangle versus how to find the volume of a box ( spoiler alert: there's no such thing as volume of a rectangle ). The calculator will assist in calculating the volume of a sphere, cylinder, cube, cone, and rectangular solids. What is volume? — Volume definition.
How to Calculate the Area. The area of a circle is: π ( Pi) times the Radius squared: A = π r2. or, when you know the Diameter: A = (π/4) × D2. or, when you know the Circumference: A = C2 / 4π. Example: What is the area of a circle with radius of 3 m ? Radius = r = 3. Area = π r2. = π × 32. = 3.14159... × (3 × 3) = 28.27 m2 (to 2 decimal places)
