The area of a circle is pi times radius squared
A 3 centimeter diameter circle has an area of 7.068 cm2
380.13 square cm.
The formula for circumference is 2 x pi x radius. For a circle of 10 feet, the cirumference would be 62.8 feet. The formula for area is pi x r2. For a circle of 10 feet, the radius would be 314.16 ft.
94.985 or approximately 95 square centimeter.
9.6 sq cm, approx.
If a circle's area is 3.14 (Pi), its radius is: about 1.
The area of a circle is its diameter times the value of PI. In most cases you can safely use the 3.14159 for the value of PI
You cannot SOLVE a circle. You can find the radius of a circle, or its diameter, or circumference or area. Or you can find the equation of a circle in the Cartesian system or in polar coordinates. Or find other characteristics of the circle. In any case, a circle cannot have an area of 24 centemeter. Apart from the fact that there is no such word - try centimetre (or centimeter). A centimetre is a measure of length, not area.
Beautiful problem !The circle has more area.If you have a circle and a square, with the circumference of the circle equal tothe perimeter of the square, then the area of the circle is always(4/pi) = 1.27324times as much as the area of the square.If you have some length of fence in your warehouse, the most land you canenclose with it is to set it up in a circle.
The exact area of a circle has never been worked out because the value of pi in the area of a circle which is pi times radius2 is only an approximation.
Area of circle can be computed using formula is A = πr2 , where, A = represented is Area of circle, π = its constant, call it as pie and value is 22/7 i.e 3.142, r = Radius of circle, which has to be squared or doubled to get area of circle.
The 'closest' value of the area of a 3-inch circle is: 7.06858347 square inches.
