How do you find the radius squared? - Answers
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. WebTo find the area from the radius, it's very easy a=\pi r^2 a = πr2 Diameter is just 2x radius, so to get the circle's area from the diameter: a=\pi (d/2)^2 a = π(d/2)2 And to find area from circumference, it's easiest to first conve r=c/2\pi \\ a = \pi r^2 r = c/2π a = πr2 Using the Circle Area Calculator Webr 2 = inner radius C 2 = inner circumference L 2 = inner surface area V 2 = volume within C 2 h = height t = wall thickness ... √ = square root Calculator Use.
