It is: 3.14*272 = 2289.06 square cm

Well, since the formula for the area of a circle is Pi (3.14) times the radius squared, you can use substitution to get an equation that looks like this: 3.14(102) ...which can be simplified to 3.14(100), which can be simplified to come up with the answer of 314 square units.
The diameter of a circle whose circumference is 314 is about 1 (99.95).
3.14*102 = 314 square centimeters
Circumference = 2 pi r = 62.8 so r = 31.4/pi = 10 Area = pi r2 = 100 pi = 314 in2

The area is 314 cm2
314 feet²Area of a circle = pi x radius²let pi = 3.14A = 3.14 x 10²A = 3.14 x 100A = 314 feet²
A circle with a radius of 10 meters has an area of 314 square meters.
A circle with a radius of 10 meters has an area of 314 square meters.
10 feet.
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.
3.14*r*r=area 3.14*100=314 or 100pi
Circumference = 314 inches implies radius = 49.97 inches and so area = 7846.02 sq inches (approx).
It is: the square root of (314/pi) = 9.997 units to 3 dp
