The... WebThe area of a circle = πr 2 square units. Now, substitute the values in the perimeter and area of circle formula, we get The area of circle = πr 2 = 3.14 (5) 2 A = 3.14 (25) A = 78.5 cm 2 The circumference of a circle = 2πr = 2 (3.14) (5) Circumference = 3.14 (10) = 31.4 cm.

Area of a Circle and its formula - mathwarehouse

WebThe area of a circle is the space occupied by the circle in a two-dimensional plane. The formula for the area of a circle is. A = πr2. where r is the radius of the circle. The value of pie is 22/7 or 3.14. Example 1 : Find the area of a ring whose outer radius is 20 cm and inner radius is 15 cm respectively. food 06790

WebThe standard equation for a circle centred at (h,k) with radius r is (x-h)^2 + (y-k)^2 = r^2 So your equation starts as ( x + 1 )^2 + ( y + 7 )^2 = r^2 Next, substitute the values of the given point (2 for x and 11 for y), getting 3^2 + 18^2 = r^2, so r^2 = 333. The final equation is (x+1)^2 + (y+7)^2 = 333 Hope this helps!
