A 20mm circle has a diameter of 20 millimeters, which is equivalent to 2 centimeters or approximately 0.79 inches. The radius of the circle is half of the diameter, so it measures 10mm. This size is comparable to a small coin, such as a dime. In terms of area, the circle has an approximate area of 314 square millimeters.
Surface area of the sphere: 4*3.14*radius2 = 314 square inches Divide both sides by 4*3.14 and then square root both sides to find the radius: Radius = 5 inches Circumference = 2*3.14*5 = 31.4 inches
Circumference = 314 inches implies radius = 49.97 inches and so area = 7846.02 sq inches (approx).

62.8 inches. the formula for a circle's area is a = pi x r squared. substitute 3.14 for pi and 314 for a. 314 = 3.14 x r squared (divide both sides by 3.14) v 100 = r squared (find the square root of both sides) v r = positive or negative 10 . since it stands for the radius of a circle, it has to be positive. now that you know the circle's radius, you can solve the circumference formula, c = 2 x pi x r. c = 2 x 3.14 x 10 c = 62.8
100pi, or approximately 314.
Knowing that the area of a circle is its radius squared times Pi, the area of a 10 ft radius circle is 100*Pi square ft, or about 314 square feet.
