How do you work out the area of a quarter of a circle?
It is: (pi*radius2)/4
How do you find the area of a semi circle or quarter circle when pi is twenty two sevenths and please include an example for both semi circle AND quarter circle?
The area of a circle is pi*r2, where r is the radius. In this case, 22/7 will be used for pi. Area of a semicircle: A semicircle is half of a circle, so the area will be half of a circle: A = (1/2)*pi*r2 Example: Find the area of a semicircle with a radius of 10 meters. A = (1/2)*(22/7)*(10)2 = (1/2)*(22/7)*(100) = 1100/7 or about 157.14 square meters Area of a quarter circle: A quarter circle is a forth of a circle, so the area will be A = (1/4)*(pi)*r2 Example: Find the area of a quarter circle with a diameter of 4 inches: (Notice that the diameter is given, so the radius in this case is 2 inches:) A = (1/2)*(22/7)*(22) = (1/2)*(22/7)*4 = 44/7 or about 6.286 square inches.
How do you find the area of a quarter circle?
You find the area of the entire circle (pi x radius^2), and then multiply it by 1/4 or 0.25.

What is the area in m2 of a quarter circle of radius 4m?
to find the area of a whole circle, use the formula Area = Pi * (Radius)^2where Pi is approximately equal to 3.14.so the area of the circle with radium = 4 m, is 16*Pi = 50.24 m^2;to find area of a quarter of this circle, divide the total area by 4to get 4*Pi= 12.56 m^2First, find the whole area.A = πr²A = π(4)²A = 50.2655Then take 1/4 of it. 12.5664 m² ■
