WebThe area of a circle is π times the radius squared, which is written: A = π r 2 Where A is the Area r is the radius To help you remember think "Pie Are Squared" (even though pies are usually round): Example: What is the area of a circle with radius of 1.2 m ? Area = πr2 = π × 1.22 = 3.14159... × (1.2 × 1.2) = 4.52 (to 2 decimals) WebWe know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So add 21 to both sides to get the constant term to the righthand side of the equation. x^2 + y^2 -4y = 21. Then complete the square for the y terms. x^2 + y^2 - 4y + 4 = 21 + 4.
