WebMar 21, 2024 · Term: Definition: Formula: Circumference of a circle: The circumference of a circle is the distance around the given circle. \(2\pi r \), where r is the radius. Area of a circle: The area of a circle is the region involved by the circle in a 2D plane. \(\pi r^{2 }\), when radius(r) is given. 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.
WebTherefore, the circumference circle equation is C = 2 πr. Example 1: If the radius of a circle is 7 units, then the circumference of the circle will be. 2 × π × 7 = 2 × 3.14159 × 7. = 43.98 units. Example 2: Suppose that the diameter of the circle is 12 feet. Then, we can use the formula πd to calculate the circumference.
