Hold it right there. That's not possible. Something's gotta give.
The area of a circle = pi R2 = pi (half the diameter)2
If the circle has a diameter of 16, then its area is 201.1(rounded).
If it has an area of 64, then its diameter is 9.03(rounded).
If it has a diameter of 16 and an area of 64, then it's not a circle.

Area of a Circle = Pi * radius squared Radius = Diameter / 2 So, Area = Pi * (16/2)^2 = Pi * 64 = 201.06 m^2 Measurement is in meters squared.
Area of a circle = pi R2R = radius = 1/2 diameter.For diameter = 16 inches, Area = pi (8)2 = 64 pi = 201.1 square inches (rounded)
area/pi = diameter 200.96/pi = 63.96755473 or 64 units in length.
The circumference of the circle with a diameter of 64 mm is 64*pi = about 201 mm
Area of a circle = pi (radius)2Radius = 1/2 of the diameterArea of your circle = pi (4)2 = 16 pi = 50.265square feet
