WebSolution: A = πr^2. where A is the area, π (pi) is a constant approximately equal to 3.14, and r is the radius of the circle, which is half the diameter. Substituting the given diameter of 2.5 inches, we get: r = d / 2 = 2.5 / 2 = 1.25 inches. A = πr^2 = 3.14 × 1.25^2 ≈ 4.91 square inches. Therefore, the area of the circle with a diameter ... WebMay 31, 2024 · Explanation: Isolate for R: Divide both sides by 2π : C 2π = 2πR 2π. R = C 2π. Answer link.

WebJun 21, 2024 · The equation basically says that C (circumference) equals 2 times (pi times radius), pi and radius being multiplied first. The answer would be C/2pi = R because you would divide 2piR by 2pi and C by 2pi to get this answer. C = 2nR is the formula for the circumference of a circle. To solve R, you would divide 2n on both sides.
