How To Find The Area Of A Circle - Area of Circle r2 or d2 4 square units where 22 7 or 3 14 The area of the circle formula is useful for measuring the space occupied by a circular field or a plot Suppose you have the plot to fence it then the area formula will help you to The area of a circle is pi times the radius squared A r Learn how to use this formula to find the area of a circle when given the diameter Created by Sal Khan and Monterey Institute for Technology and Education

How To Find The Area Of A Circle

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) The formula for the area of a circle is π x radius2, but the diameter of the circle is d = 2 x r 2, so another way to write it is π x (diameter / 2)2. Visual on the figure below: π is, of course, the famous mathematical constant, equal to about 3.14159, which was originally defined as the ratio of a circle's circumference to its diameter.

How To Find The Area Of A CircleThe area of a circle when the radius 'r' is given is πr 2. The area of a circle when the diameter 'd' is known is πd 2 /4. π is approx. 3.14 or 22/7. Area (A) could also be found using the formulas A = (π/4) × d 2, where 'd' is the radius and A= C 2 /4π, where 'C' is the given circumference. The formula to calculate the area of a circle using radius is as follows Area of a circle r 2 And to calculate the area of a circle using diameter use the following equation Area of a circle d 2 2 where is approximately equal to 3 14 It doesn t matter whether you want to find the area of a circle using diameter or

How To Find Circumference With Radius And Diameter

Diameter. The diameter \hspace {0.2em} (d) \hspace {0.2em} (d) is the length of a line segment that passes through the center of the circle and touches it on both ends. It is twice the radius. d = 2r d = 2r. Circumference \hspace {0.2em} (C) \hspace {0.2em} (C) refers to the perimeter of a circle. It is the length of the circle’s boundary.
