WebHow to calculate square feet For a square or rectangular shaped room or area, measure the length and width of the area in feet. Then, multiply the length and width figures together. As an example, if your room measures 14 feet wide by 18 feet long, your calculation is 14 × 18 = 252 square feet. WebUse the distance formula to find the length of the diameter, and then divide by 2 to get the radius. Then find the midpoint of the diameter which will be the center of the circle. Now …
WebThe area of a circle is π times the radius squared, which is written: A = π r 2 Where A is the Area r is the radius To help you remember think "Pie Are Squared" (even though pies are usually round): Example: What is the area of a circle with radius of 1.2 m ? Area = πr2 = π × 1.22 = 3.14159... × (1.2 × 1.2) = 4.52 (to 2 decimals) Squaring the circle is a problem in geometry first proposed in Greek mathematics. It is the challenge of constructing a square with the area of a circle by using only a finite number of steps with a compass and straightedge. The difficulty of the problem raised the question of whether specified axioms of Euclidean geometry concerning the existence of lines and circles implied the existence of such a squ…
