Formula of quadrant of circle
WebFirst you need to know that the equation for a circle is (x-a)^2 + (y-b)^2 = r^2 where the center is at point (a,b) and the radius is r. so for instance (x-2)^2 + (y-3)^2 = 4 would … WebA quadrant is exactly one fourth of any circle. Area of a quadrant = (1/4)πr2 Perimeter of a quadrant = ( (π/2) + 2)r It has 90 degree angle at the center. Example 1 : Find the area of quadrant with radius 7 cm. Solution : Here r = 7 cm and π = 22/7. = (1/4) ⋅ (22/7) ⋅ (7)2 = (1/4) ⋅ (22/7) ⋅ 7 ⋅ 7 = (1/4) ⋅ 22 ⋅ 7 = (1/2) ⋅ 11 ⋅ 7
