WebA circle is a locus of all the points equidistant from a fixed point to the outer boundary. Learn its definition, construction of the circle, formulas for area and circumference with solved examples. Login Study Materials NCERT Solutions NCERT Solutions For Class 12 NCERT Solutions For Class 12 Physics NCERT Solutions For Class 12 Chemistry WebSince a circle is a two-dimensional figure, it has an area and a perimeter. Let us discuss the formula for area and the circumference of a circle. Area of Circle The area of the circle is the space occupied by the shape circle. The formula to calculate the area is given by. Area of Circle, A = πr 2 Square units. Circumference of Circle: WebIllustration 7: A foot of the normal from the point (4, 3) to a circle is (2, 1), and the diameter of the circle has the equation 2x – y = 2. Then, find the equation of the circle. Solution: The line joining (4, 3) and (2, 1) is also along a diameter. So, the centre is the point of intersection of the diameter 2x – y = 2 and the line organic chemistry helper
