WebPrecalculus. Find the Center and Radius x^2+y^2=4. x2 + y2 = 4 x 2 + y 2 = 4. This is the form of a circle. Use this form to determine the center and radius of the circle. (x−h)2 +(y−k)2 = r2 ( x - h) 2 + ( y - k) 2 = r 2. Match the values in this circle to those of the standard form. The variable r r represents the radius of the circle, h ... WebFeb 28, 2016 · See the explanantion This is the equation of a circle with its centre at the origin. Think of the axis as the sides of a triangle with the Hypotenuse being the line from the centre to the point on the circle. By using Pythagoras you would end up with the equation given where the 4 is in fact r^2 To obtain the plot points manipulate the equation as …

WebFor the region OPQO, the limits of integration are x = 0 and x = 5. Given equation of the circle is. x 2 + y 2 = 25. ∴ y 2 = 25 – x 2. ∴ y = ± 25 - x 2. ∴ y = 25 - x 2 ... [∵ In first quadrant , y > 0] ∴ Required area = 4 (area of the region OPQO) = 4 × ∫ 0 5 y ⋅ d x. = 4 × ∫ 0 5 25 - x 2 ⋅ d x. WebSeller information. CHINA.
