Step Three: Find How Many Bricks Fill the Wall. You can determine the number of bricks needed to cover your area by dividing the square footage of the area to be covered by the brick's square footage (wall sq ft ÷ brick sq ft).To calculate the square footage of a circle, use the formula A = πr², where A represents the area and r is the circle's radius. For example, if the radius is 5 feet, the square footage is π (5²) = 25π square feet, or approximately 78.54 square feet. This formula works for circles of any size by substituting the appropriate radius.It is interesting to compare the area of a circle to a square: A circle has about 80% of the area of a similar-width square. ... Calculating a square hole: 0.4 × 0.4 = 0.16 m 2; 2. Taking 80% of that (estimates a circle): 80% × 0.16 m 2 = 0.128 m 2; 3. And the volume of a 1 m deep hole is: 0.128 m 3; Choose the useful one based on the data you have. This calculator will automatically estimate all of the other values. The first one is based on the radius of the circle. The diameter equals the length of two radiuses. d = 2 r. d=2r d = 2r. Area of a circle: d = 2 a π. d=2\sqrt {\frac {a} {π}} d = 2 πa.All you need here is the radius. The sq. ft. formula in case of a circle is: Square footage Circle= π*Radius*Radius. Where: π= 3.14159265359. Square: Square footage Square= Side*Side. Rhombus: In this case you need its base and height. If you enter these data the Square Foot Calculator can quickly do the job for you. Circular segment - is an area of a "cut off" circle from the rest of the circle by a secant (chord).
