Area of a circle = pi*radius2
A square number.
I don't know if this is what you mean, but to make a normal number a square number, you have to times it by itself*****I suspect though, that the answer is as follows:A square number is one that is the product of some integer multiplied by itself. This second integer is the square root of the original number. Thus, 9 is a square number since 3*3 = 9
Assuming that the question is in the context of complex number, the product of any real number with itself (its square) is a real number.
A perfect square number is a number that can be expressed as the product of two same common integers. For instance, 16 is a perfect square since it is expressed as 4 x 4. 14 is not the perfect square since it can't be expressed as two common integers. The factors of 14 are 2 and 7.
Anywhere that a curve appears, including a circle. The diagonal of a square or most rectangles.
That would depend on its radius because the area of a circle is pi times radius squared
Let's call the number 'K' ... the side of the square and the radius of the circle.-- the area of the square is [ K2 ]-- the area of the circle is [ (pi) K2 ]-- The ratio of the circle to the square is [(pi) K2 / K2 ] = pi
Half the square root of the square radius equals the circle 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.
The general formula for area of a circle is A=(pi)r2, the product of pi and the square of the radius. In this instance, the area equals pi X 92 = about 254.47.
The same as half the side of the square, as the radius of the circle is half its diameter, and the diameter of the circle is equal to the side of the square.
Area- square the radius of the circle and multiply it by pi Circm.- multiply the radius by 2 and then multiply that number by pi
No, that process gives you the circumference of the circle.To find the area of a circle, multiply 3.14 by the square of the radius.Notes:1). The square of the radius means (radius) times (radius).2). The number "3.14" is not exact. It's an approximation for the number "pi".
pi times its radius squared
Pie x radius squared You must know the radius.
Eighty square centimeters
If the area of a circle is 1519.76 square meters, the radius is 21.994422761843005 meters.
