A quadrilateral has four sides. A circle does not have four sides. Therefore, a circle is not a quadrilateral.
Three choices, depending on what information you have about the circle: -- Multiply the radius by itself, then multiply the result by (3.1416). -- Multiply the diameter by itself, then multiply the result by (0.7854). -- Multiply the circumference by itself, then multiply the result by (.07958).
