Circumference = 60 miles
ie 2*pi*r = 60 miles, where r is the radius.
So r = 30/pi = 9.55 miles (approx)
and then area = pi*r2 = 286.48 sq miles.
That depends whether the "10-mile circle" refers to the circle's radius, its diameter, or its circumference. Assuming it is the diameter, divide it by 2 (to get the radius), then use the formula: area = pi x radius2.
Assuming that "1 inch round circle" refers to a circle whose circumference is 1 inch, its area is 51.34 sq mm.
If you have a circular area with a 50-mile radius, the area of the circle is approximately 7,854 square miles (rounded).
It is greater by 18.8 feet.
the M25 is reported to be 117 miles long , so if it was a circle the area can be calculated C = 2 pie R where c is circumference and R the radius so R = 117/2 Pie = 18.6 miles approx so the area A = pie R squared A=1087 miles if it was a circle which it isnt so i would take away somewhere between 5 and 15 per cent 5% of 1087 = about 54 15% about 162 so about 925 - 1033 square miles , although ive read somewhere its only about 600 square miles so maybe my maths is a bit dodgy when im drunk
A circle with a circumference of 188 miles has an area of about 1,800,055 acres.
A 45-foot circumference circle has an area of: 161.1 square feet.
The area of a circle with a circumference of 5 miles is approximately 1.26 square miles.
If the area is a circle and the radius of the circle is 21 miles, the distance around the circle (circumference) is 131.95 miles. The area of that circle is 1,385.4 square miles.
The area of a circle with a circumference of 87 miles is: 385,472 acres.
If the circle's diameter is two miles, the area would be: 8042 acresA diameter radius of two miles is 12.5 square milesIf the circle's circumference is two miles, the area would be: 203.7 ac
