By dividing the diameter by 2 will give the circle's radius. Area of any circle = pi*radius squared.
It is: (pi*radius2)/4
The area sector of a circle needs pi to work it out.
Yes. That is often how pie charts work.
The area of a circle is the number of square units inside that circle, if each square in the circle to the left has an area of 1cm2, you could count the total number of squares to get the area of this circle. However, it is easier to use one the following formulas; A=.r²or A=pi times r times r, where A is the area and r is the radius.
You cannot. Excel can only work in approximations. You would ned an infinite number of cells to generate a perfect circle.

By dividing the diameter by 2 will give the circle's radius. Area of any circle = pi*radius squared.
Area of any circle = pi*radius squared
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
It says so in the formula
Pi times the square of the radius.
It is: (pi*radius2)/4
The area sector of a circle needs pi to work it out.
Yes. That is often how pie charts work.
The area of a circle is equal to that of a triangle whose base has the length of the circle's circumference (distance around the circle) and whose height equals the circle's radius which comes to Pi multiplied by the radius squared. Area of Triangle 1/2 *base*height
