WebMay 30, 2024 · Explanation: Isolate for R: Divide both sides by 2π : C 2π = 2πR 2π. R = C 2π. Answer link. WebMay 18, 2013 · If we divide an n sided equilateral polygon into n triangles (which are generated by the lines to centre from the vertices), the angle at the centre 2 π n. Let each side be x and the distance from the centre to any vertex be r. The rest two angles are same = θ (say) So, 2 θ = π − 2 π n θ = π 2 − π n.

WebSolve for h A=2pir(r+h) Step 1. Rewrite the equation as . Step 2. Divide each term in by and simplify. Tap for more steps... Divide each term in by . Simplify the left side. Tap for more steps... Cancel the common factor of . Tap for more steps... Cancel the common factor. Rewrite the expression. WebA = 2 π r 2 + 2 π r h. Since 2 π is common on both sides of the + so I will take it out. A = 2 π ( r 2 + r h) Now, divide both sides by 2 π. A 2 π = r 2 + r h. Then, we can divide by the h. … WebThe formula c=2 pi r solve for r - r=C/(2pi) This is the formula for Circumference C of a circle given the radius r, where pi=22/7 or 3.14 or 3.14159 or 3.1416.
