PLEASE HELP ME I REALLY NEED HELP PLEASEEEE If a circle has an area of 12πcm² and a diameter line AB, what is the length of arc

Softa [21]

Answer:

"Let's say it is equal to 45 degrees, or π/4. Calculate the arc length according to the formula above: L = r * Θ = 15 * π/4 = 11.78 cm . Calculate the area of a sector: A = r² * Θ / 2 = 15² * π/4 / 2 = 88.36 cm² . You can also use the arc length calculator to find the central angle or the radius of the circle. "
