Pie x radius squared You must know the radius.
The answer depends on their relative size: is the circle inside the square, the square inside the circle or something else?
The diagonal of the square.
The is not stated that the circle inside the square was the greatest possible circle, so all one can say is 8pi at most.
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.
Pie x radius squared You must know the radius.
This is the definition of the area of a circle. The formula to find area is given as pi times the radius raised to the second power, where pi is approximated as 3.14.
If the circle is inside the square, four.
That would depend on its radius because the area of a circle is pi times radius squared
The answer depends on their relative size: is the circle inside the square, the square inside the circle or something else?
The diagonal of the square.
You find the area of the whole square first. Then you find the area of the circle inside of it And then subtract the area of the circle from the area of the square and then you get the shaded area of the square
The is not stated that the circle inside the square was the greatest possible circle, so all one can say is 8pi at most.
Say the radius of the circle is x. This makes the area of the circle pi x2. Since the length of the square's sides is the diameter of the circle, 2x, its area is 2x * 2x = 4x2. The percentage occupied by the circle is the area of the circle divided by the area of the square times 100 pi/4 x 100; pi/4 x 100 = 100pi/4 = 25pi = 78.6%.
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.
A circle is not a number, it is a 2-dimensional shape. A number can have a square root, not a shape. So, a circle cannot have a square root!.
The area of a circle is the number of square units inside that circle, if each square in the circle to the left has an area of 1cm2, you could count the total number of squares to get the area of this circle. However, it is easier to use one the following formulas; A=.r²or A=pi times r times r, where A is the area and r is the radius.
