Area of a circle is pi times radius squared.
Any formula involving a circle will have "pi" in it. Area = pi* radius * radius Circumference = pi * diameter = pi * radius * 2 ( the diameter is just 2 times the radius) Quick way: A = pi r squared C = pi D
Oh, happy little accidents happen sometimes! Non-examples of the area of a circle could be the perimeter of the circle, the diameter of the circle, or the volume of a sphere. Remember, mistakes are just happy little learning opportunities in disguise.
If i remember the 'ol math class circle area is equal to radius squared times pi so 20x20x3.14 = 1256 meters squared
Area of a circle = pi*radius2 measured out in square unitsfor pi use this number 3.14159and remember the radius of a circle = half the diameter.----------------------------------------------------------------Thus a circle with a 10 inch diameter would have an area of:Radius = diamiter/2, which is 10/2= 53.14159 * (5*5) = 78.53975 square inches
The area of a cylinder is equal to pi times radius squared times height. It helps to remember that it's simply the area of a circle times height.

The approximate area of the circle in question is 85 square meters. In order to figure this out, remember you need to break it down into figuring out the square root of the chord. You also need to figure out the area beneath an arc in the circle.
If they show only the area of the circle, then multiply the area times pi (I prefer you use a calculator if your not that great at math). Remember Pi equals: 3.14 or 22/7. 3.14 is easier to use in my opinion.
The surface area of a circle can be found using the formula A = πr^2, where A is the area and r is the radius of the circle. Simply square the radius and multiply it by π to calculate the surface area.
Area of a circle = pi*radius2
Area of a circle = Pi * radius2
Area of a circle = pi*radius2
