Circumference of circle: 31.4 inchesArea of circle: 78.5 square inches

Diameter = 6 inches Radius = 3 inches Circumference = 2 x pi x radius = 18.84955592 inches

It is a line, which is 11 inches long, from the circumference of a circle to its centre.

If r = 8 inches then C = 50.27 inches.

If Mark makes a circle, that circle would have a circumference of 12 inches. The formula for circumference is pi times diameter, so the circumference divided by pi will give you the diameter of 3.82 inches. Divide this by 2 to get the radius of 1.91 inches. Area of a circle is pi times the radius squared. 1.91 squared is 3.6481. Multiply this by pi to get 11.46 square inches of area inside the circle. A circle is always the most efficient use of space possible given a fixed perimeter. If Mark makes a square with equal sides where all sides are 3 inches, the area would be 9 square inches. 3 X 3 = 9
