WebDec 14, 2024 · You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm². Finally, you can find the diameter - it is simply double the radius: D = 2 * R = 2 * 14 = 28 cm. Use our circumference …
WebA = C [set area equal to circumference] πR2 = 2πR [use formulas for area and circumference of a circle] R2 = 2R [divide both sides by π] R2 – 2R = 0. R (R – 2) = 0. So the solutions are R = 2 and R = 0. The first solution, R = 2, gives us a circle with an area of 4π square units and a circumference of 4π linear units. high carbon dioxide in blood meanWebSolution: Estimate 3 × 8 2 = 3 × 64 = 192.
