How do you find the diamter of a circle if you know the area?
In order to find the diameter of a circle if you have the area is to rearrange the formula for the area of a circle to put diameter as the unknown, like so: PIE*d = Area of a Circle d = (Area of a Circle) / PIE Therefore if the area of your circle is 40cm, 40/PIE = 12.73cm and that's the diameter.
How do you find the radius of a circle if area is 81 pi?
Divide the 81 pi by pi, then square root it. (Use the formula for area of circle, which gives 81pi=pi*radius squared, but rearrange to find the radius). i.e. it's the square root of 81
Formula to find the area of circle?
Area of a circle = pi*radius2
What is the formula for the circumference of a circle from the area?
In order to convert the area of a circle to the circumference of the circle, divide by the radius and multiply by two. The formula for the circumference of a circle is pi times the diameter.
What is the formula for finding the area of a semi-circle in terms of pi?
semi means half A semi-circle is half a circle The formula for the area of a circle is A = (Π * r^2) Area of semi circle = (Π * r^2) ÷ 2

What is the formula of the sector of the circle?
There is no specific formula for a sector of a circle. There is a formula for its angle (at the centre), its perimeter, its area.
Formula and result of area of circle?
The formula for the area of a circle is: Area = (pi) x (Radius)2 . When you know the radius of the circle and you use it to calculate the area of the circle, the result will be equal to (pi) x (Radius)2 .
