A circle labeled "metal" with a smaller circle labeled "aluminum" completely inside it
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.
You are describing a railroad crossing sign.
It will represent 1/360 of a circle's circumference of 360 degrees
The director circle of a circle with radius r is a concentric circle with radius r*sqrt(2).
Yes
bird circle inside the animal circle
True
has wings in outer circle (*bigger circle) insect inside inner circle (*smaller circle)
A circle labeled "metal" with a smaller circle labeled "aluminum" completely inside it
It is r*sqrt(2) = 1.414*r, approx.

bottom of a bowl, a ball, a drinking cup top and bottom, a circle block, a head, tennis ball, soccer ball, basketball, heel of foot, bottom of toes, dell circle on a computer, circle picture, top and bottom of pipes, a circle, a zero as a number, o as a letter, inside of a Q, inside of a letter d, inside a letter b. that is 20 circles
Consider a circle of radius r. You want a square inside of that circle. The diameter of the circle is 2r and this is also the length of the diagonal of the square. Now the Pythagorean theorem says that if the side of the square inside the circle is of length s. 2s2 =4r2 this come for a2 +b2 =c2 where a and b are s and c is 2r so we have s2 =2r2 Then length of the side OS the square is r(square root of 2) or s=r(square root of 2)
