The circumference of a circle if the diameter is 7 inches and Pi is 3.14 is: about 21.98 inches.
Diameter = 314/pi feet
Approximatly 50inches
you divide by pi (3.14) then take the square root, then multiply by 2 and multiply by pi (3.14)...in that order i.e. if you have a circle with area of 314 square inches, you take the 314 and divide by 3.14...you get 100...then you take the square root of 100...you get 10...then you multiply by 2...you get 20...then you multply by 3.14...you get 62.8 inches...thats the circumference of a circle with an area of 314 square inches
It's simple, just multiply de diameter of the circle by the pi number: 3.141592653.... the result is 31.14 cm, or 314 milimeters.
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
The diameter of a circle whose circumference is 314 is about 1 (99.95).
Diameter = 314/pi feet
Circumference = 314 inches implies radius = 49.97 inches and so area = 7846.02 sq inches (approx).
Approximatly 50inches
100*pi≈314 feet
100pi, or approximately 314.
If you mean 3.14 for pi then the circumference is: 7*3.14 = 21.98 cm

The circumference is 62.815 units.
about 314
Tells you the answer is 2*sqrt(314*pi) inches, which is approximately 62.82 inches Seriously though. Use metric units in maths it makes everything just work!
