Equation of a circle in quadrant 3
WebArea of Quadrant. Area of quadrant is the space occupied by one-fourth part of a circle and is equal to one-fourth of the area of a circle. The formula for the area of a quadrant is 1/4 × area of a circle or is equal to πr 2 /4. And the units for area of quadrant is m 2, inch 2, cm 2.. Let us learn more about the area of quadrant, the formula of area of … WebOct 24, 2016 · Explanation: The standard form for the equation of a circle is: (x −h)2 + (y −k)2 = r2 where (x,y) is any point on the circle, (h,k) is the center point and r is the radius. Use the standard form to write two equations using points A and B: ( − 2 − h)2 +(0 −k)2 = r2 (5 −h)2 + (1 − k)2 = r2 Because r2 = r2, we can set the left sides equal:
