Is the area of a circle bigger than the area of a square?
It depends on the diameter of the circle and the width of the square, if they are the same then the answer is no. If you draw yourself a square then inscribe a circle with a radius of half the length of a side of the square, the circle will fit inside the square but the corners of the square will be outside the circle. Thus by inspection the area of the square is larger than the area of the circle.
How much greater is the area of the square than that of the circle if the diameter of the circle is 10?
The answer depends on the square!
Does the center of a circle turn faster than the outside?
no
What is the area of circle with a raduis of a mixed number?
Every mixed number is more than ' 1 '. If the radius of the circle is more than '1', then the area of the circle is more than (pi) square units.
Inscribe a circle within a square How would you find the area of leftover parts of the square that is the parts of the square that are not within the circle?
Find the total area of the square: length times height. Next, find the total area of the circle: Pi times radius to the second power, or Pi(r squared). If you are doing this by hand, 3.14 is usually acceptable for Pi. Once you have the are of both the square and the circle (the area of the circle should be smaller than that of the square), subtract the area of the circle from the area of the square. The difference is the area of those extra corners of the square that the circle does not occupy. It is actually quite simple. This demonstrates the danger of thinking in words rather than pictures.
