Which are true about the area of a circle? Check all that apply. ~The units are always squared. ~The area can be found when given the diameter by first finding the radius. ~Circumference can be used to find area.
The area of a circle calculator helps you compute the surface of a circle given a diameter or radius. Our tool works both ways — no matter if you're looking for an area-to-radius calculator or a radius to the area one, you've found the right place .
Task 1: Given the radius of a circle, find its area. For example, if the radius is 5 inches, then using the first area formula calculate π x 5 2 = 3.14159 x 25 = 78.54 sq in. Task 2: Find the area of a circle given its diameter is 12 cm. Apply the second equation to get π x (12 / 2) 2 = 3.14159 x 36 = 113.1 cm 2 (square centimeters).
The formula to find the area of a circle is to square the radius and multiply by π. The inverse of this is divide the area by π, then square root. 900π ÷ π = 900. The square root of 900 is...
