Since the formula for the area of a circle squares the radius, the area of the larger circle is always 4 or 2 2 times the smaller circle. Think about it: You are doubling a number which means ×2 and then squaring this ie squaring 2 -- which leads to a new area that is four times the smaller one. Circle is a particular shape and defined as the set of points in a plane placed at equal distance from a single point called the center of the circle. We use the circle formula to calculate the area, diameter, and circumference of a circle. Formula. The formula used to calculate circle area is: A = π x ø/ 2 2. Symbols. A = Circle area; π = Pi = 3.14159 ø = Circle diameter; Diameter of Circle. Enter the diameter or two times the radius of a circle. Area of Circle. This is the area contained within a circle with the specified diameter.

The formula above is the one used in our area of a circle calculator. How to calculate the area of a circle? Calculation is easy once you have measured the circle's radius or diameter, or if you know it from plans and schematics: just plug the numbers into the formulas above use our area of a circle. The formula for the area of a circle is pi multiplied by the radius of the circle squared. The radius of the circle is the length of a straight line stretching from the center of the circle to the line of circumference. It is equal to half the diameter. The approximate value of pi is 3.14.

An easy to use, free area calculator you can use to calculate the area of shapes like square, rectangle, triangle, circle, parallelogram, trapezoid, ellipse, and sector of a circle. Formulas, explanations, and graphs for each calculation. Area of a triangle calculation using all different rules, side and height, SSS, ASA, SAS, SSA, etc. This formula will calculate the area of a circle given its radius. How It Works. The area of a circle is given by PiRadius^2 where Pi is a constant approximately equal to 3.14159265. Excel has this constant built in as a function with no parameter inputs PI. The POWER function will take any number and raise it to the power of any other number. The area of a circle is determined by the formula: A = π r 2. You can easily calculate the area of a circle in under a minute. All you need is a calculator, a circle to measure and a. 10/12/2018 · The conversion of a given diameter to square feet uses a simple formula for determining the area of a circle. This can be useful for deciding how much paint to buy to cover a circular ceiling or perhaps how much grass seed to purchase for a circular-shaped patch of lawn. The formula for the area of a circle is the.

Square footage is the length of your room times the width. For a circular room, measure the diameter length across the circle, divide by 2 to get the radius length across half the circle, multiply by pi and square it. The formula for the area of a circle is πr^2, and Pi π= 3.1416. You probably think of a radius as a property of a circle in two dimensions or of a three-dimensional sphere, but mathematicians also use the term to refer to certain distances in regular polygons. Radius of a square may also refer to the radius of a circle associated with a square.
