A square doesent have a radius only circles do. :)
If the square touches the circle from the outside then its area is 6*6 = 36 square inches
If you mean square units within a circle then it is:- Area = pi*radius squared
Since 'radius' usually applies to circles, a circle with a radius of 17 feet would have an area of 907.92 square feet.
Divide the diameter by 2 to get the radius then square the radius, and finally multiply by pie (3.14)
If you are talking about circles determine the radius by dividing the Area by pi and take the square root of the result. Then multiply the radius by two times pi.
This is assuming that the four circles are arranged in a square, with each circle touching two other circles at their tangents.First, you need to determine the area created by drawing a square between the center points of all of the circles.Circle radius = 10Side of square = 10 * 2, or 20Area of square = 20 * 20, or 400Now that you have that area, you can deduct the four quarters of the circles inside the square area. You can do it the long way, but four quarters of identical circles equals the area of one of the circlesArea of circle = pi * r^2= pi * 100=3.14159 *100=314.159Square Area - (4) quarter circle area400 - 314.159= 85.841
The area of a circle is directly proportional to the square of its radius. If two circles have radii R1 and R2 , then the ratio of their areas is ( R1/R2 )2
about 45.82576 area of square = side*side = side ^ 2 2100 = s^2 2100^0.5 = s s ~45.82576
No Radius in a SquareA radius is a feature of a circle, not a square. A square, whatever its area, does not have a radius.
When you try to figure out an area of a circle, you square the radius, then multiply it by pi to get the area of a circle. A radius square is radius x radius, or radius squared.
Squares: Take two sides and multiply them against each other, ex. 3.5•3.5= the area. Rectangles: Same as squares. A square is a rectangle. Circles: Radius times radius times pi equals area.
