Circumference of any circle = (pi) x (diameter) Diameter = 2 x radius

Circumference: 14*pi mi Area: 49*pi square mi

The area of a circle is equal to pi times r2. If D is 14 miles, then r is 7 miles. Pi is approximately 3.14 and 72 is 49. So 3.14 x 49 = 153.86 square miles.

22.52 x pi = 506.25pi sq miles. Taking pi as 355/113 gives 1590.43 sq mi

Answer: 123 km = 76.4286 mi.

The circumference of a circle with diameter d is pi*d So if d = 8mi then circumference = 25.13 mi.

That depends on what is meant by 38 mi but the circumference of any circle is 2*pi*radius or diameter*pi

Circumference = pi*diameter So diameter = circumference/pi = 9.87 mi

Using 3.14 as Pi the area of circle is: 200.96

Using 3.14 as Pi the area of circle is: 120.7016
