radius square mutiplied by pi.thus pi equals 22/7 or 3.143.
the formula for the area of a circle is 3.14 x radius squared
The formula to find the area of a circle is: A = pi * r2
TTr2 [Pi r squared] finds the area of the circle. TT x d [Pi x diameter] finds the circumference of a circle]
The formula used to calculate the area of a circle is A r2, where A represents the area and r is the radius of the circle.
The formula for calculating the area of a circle is A r2, where A represents the area and r represents the radius of the circle.
The area of a circle can be found with the formula (pi)r^2
Area formula for circle= --,,- r 2
The formula to find the area of a circle is pi x the radius squared.
The formula for double the area of a circle
Area of a circle = pi*radius2
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.
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 .
