The question is assumed to be asking whether the area of a circle can "come out even", or be written as an exact number without rounding or approximating. The answer is yes ... but then the radius (or circumference) of the circle couldn't be perfectly written. Look at it this way: We know that 'pi' is the constant that relates the area of a circle to its diameter: A = (pi)R2. You can re-write this simple formula as: A/R2 = pi. Since 'pi' is an irrational number, then the fraction A/R2 is an irrational number, meaning that either 'A' or 'R2' (or both) must be irrational.

How can we Explain descriptively a way to find the area of circle?
The area of a circle is pi times the circle's radius squared = pi*radius2
Define the term gulf?
A large area of Sea that has land almost all the way around it
What is the shortest way to find the area of circle?
pi r2
Can decimals be divided by decimals?
Yes. Assuming these decimals are real numbers, you can divide them by each other. For example: If somebody asks you to find out the radius of a circle that is 3.5m2 then you would have to use the area formula for a circle (area = πr2). So you have 3.5 = πr2 r2 = 3.5/π See how we have a decimal (3.5) divided by another decimal (π). We know that the radius must exist because there is no way that a circle with an area of 3.5m2 is impossible. A decimal is just way of representing a number. The form in which it is written doesn't define what can be done with it.
If I have 10.920 meter area so how many square meter in area is it?
What do you mean by a "10.920 meter area"? A meter is a measure of length, which cannot be used to define an area UNLESS it is qualified in some way. eg is your area 10.920 meters across in all directions, ie it is a circle with a diameter of 10.920 meters? eg Is your area surrounded by a 10.920 meter long fence which encloses the area; ie the perimeter of the area is 10.920 meters - even this is incomplete as there are many different shapes with different areas which ALL have a perimeter of 10.920 meters (the largest area is when the shape is a circle and the 10.920 meters is the perimeter of the circle).
Define the word symbol?
like a no smoking sign it has a cigarette and a circle and line and its mostly a way of saying something without words
Where is the arctic in the US?

How do you prove sin90equalsto 1?
Make a diagram. One way to define sine and cosine is with the unit circle - a circle with a radius of 1 unit. For any point on the circle, the sine is the y-component, while the cosine is the x-component.
Does the radius affect the area of a circle?
Yes the radius does affect the area of a circle. In fact to find the area of a circle people need to know the radius. The radius is half way between the middle of a circle to any of it's edges. The formula for the area of a circle ispi*radius squaredYou must first find the square of the radius and multiply it by pi(3.14.) For more help go to Wikipedia.com and type circle.
Although locus of points can be used to define a straight line and circle more complex shapes such as parabolas must be defined a different way?
False
What is the area in feet of a 12 inch circle?
There's no way to express area in feet - it needs to be square feet. A circle of radius 12" has an area of pi sq. ft. ~= 3.141 sq. ft. A circle of diameter 12" has area pi/4 sq ft ~= 3/4 sq. ft.
Is circumference larger than radius?
Yes it is. Circumference is the whole area of the circle. Radius is from the middle to the side of the circle. Yes it is. The radius it half way across the circle from the center, while the circumference is all the way around the circle. The diameter is all the way across the circle, while being twice the radius. The circumference is about 3.14 times the diameter (or Pi if you prefer).
