The area of a circle with a circumference of 9.42 inches is: 7.06 square inches.
Circumference = 314 inches implies radius = 49.97 inches and so area = 7846.02 sq inches (approx).
100*pi≈314 feet
A circle with a radius of 10 meters has an area of 314 square meters.
That is the formula for calculating the area of a circle with a 10 unit radius. The answer is 314 sq units.
1 x 314 and 2 x 157
Circumference = 314 inches implies radius = 49.97 inches and so area = 7846.02 sq inches (approx).
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
The circumference is 62.815 units.
Circumference = 2 pi r = 62.8 so r = 31.4/pi = 10 Area = pi r2 = 100 pi = 314 in2
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!
The diameter of a circle whose circumference is 314 is about 1 (99.95).
100pi, or approximately 314.
C=2*pi*r A=pi*r^2 so you divide the circumference by 2*pi (~6.28), then square that and multiply by pi (~3.14) and that would get you the area of a circle i.e. if Circumference = 62.8 inches...you divide by 6.28 and get 10, then you square that (10*10=100), then you multiply by pi...100*3.14= 314 square inches.
Diameter = 314/pi feet
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
about 314
