Solve area of circle
WebThe formula to find a circle's area π ( radius) 2 usually expressed as π ⋅ r 2 where r is the radius of a circle . The area of a circle is all the space inside a circle's circumference . In diagram 1, the area of the circle is indicated by the blue color. The area is not actually part of the circle. Remember a circle is just a locus of points. WebApr 11, 2024 · The sector area formula may be found by taking a proportion of a circle. The area of the sector is proportional to its angle, so knowing the circle area formula, we can write that: α / 360° = Sector Area / Circle Area. Angle conversion tells us that 360° = 2π. α / 2π = Sector Area / πr². so: Sector Area = r² × α / 2

WebExample: find the area of a circle. Task 1: Given the radius of a circle, find its area. For example, if the radius is 5 inches, then using the first area formula calculate π x 5 2 = 3.14159 x 25 = 78.54 sq in.. Task 2: Find the area of a … 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.
