Circles that lie completely within the fourth quadrant of the Cartesian plane have their centers in the fourth quadrant and have a radius smaller than the distance from the center to the x-axis and y-axis. In other words, the circle's center coordinates (x, y) must both be positive, and the radius r must be less than both x and y. This ensures that the entire circle falls within the boundaries of the fourth quadrant.
A circle with centre (x0, y0) and radius r has the equation of:
(x -x0)² + (y - y0)² = r²
By writing the equation of any circle in this form its centre and radius can be determined.
To completely lie within a quadrant, the centre of the circle must be more than r away from the y- and x-axes:
If either x0 or y0 (or both) is exactly r away from the y- or x-axis then the circle is on boundary between quadrants, and if either x0 or y0 (or both) is less than r away from the y- or x-axis, then the circle is in more than one boundary.
f x0 < r from the y-axis then the circle is in quadrants I and II, or y0 < r from the x-axis then the circle is in quadrants III and IV; if both less than r away from their respective axes, the the circle is in all four quadrants.
An angle in a quadrant refers to an angle formed by a ray that originates from the origin of a coordinate plane and lies within one of the four quadrants. Each quadrant is defined by the x-axis and y-axis, and angles in a quadrant are measured in a counterclockwise direction from the positive x-axis. The measure of an angle in a quadrant typically ranges from 0 degrees to 90 degrees.
A circle with 5 circles within it...that's the symbol for it
Hey, this one is nice! I will venture the following: * 3: make them tangent in one point, with no intersection * 2: make them have a small intersection, ie. crossing in two points * 1: make them tangent from the inside * 0: make one fall completely within the other Giving the explanation would just be killing the imagination.
The answer will depend on the configuration of the circles: they could overlap only pairwise - a bit like the Olympic rings, or they could have regions where several circles overlap. One configuration could be as follows. In order to visualize the circles, draw them yourself, following these instructions carefully:- Draw your first circle, maybe about 8cm in diameter. Write '5' in the center. Draw another circle to the left, with its center about 0.5 cms inside the circumference of the 1st circle, ensuring that the '5' is within this second circle. Write a small '1' just right of center of this second circle, and '9' in the open space of this second circle, i.e. to the far left. Draw a lower circle in the same way, with its center about 0.5 cm up from the circumference of the 1st circle, ensuring that the '5' is within this third circle. Write a small '4' just above center of this third circle, and '6' in the open space of this third circle, i.e. at the bottom. Draw a circle to the right in the same way, with its center about 0.5 cm in from the circumference of the 1st circle, ensuring that the '5' is also within this fourth circle. Write a small '3' just left of center of this fourth circle, and '7' in the open space of this fourth circle, to the far right. Finally, draw an upper circle, with its center about 0.5 cm down from the circumference of the 1st circle, ensuring that the central '5' is also within this fifth circle. Write a small '2' just below center of this fifth circle, and write '8' in the above open space of this circle. -------------------- You will have five circles and will have used each number 1 to 9 only once, each within its own space. Your central circle will have 5,1,4,3,2 (total 15) within its boundaries. The left circle will have 9,1,5 (total 15) within its boundaries. The bottom circle will have 5,4,6 (total 15) within its boundaries. The right circle will have 5,3,7 (total 15) within its boundaries. The top circle will have 8,2,5 (total 15) within its boundaries. And all the requirements of this puzzle are fulfilled. -------------------------------------------
Draw your Venn Diagram as three overlapping circles. Each circle is a set. The union of the sets is what's contained within all 3 circles, making sure not to count the overlapping portion twice. An easier problem is when you have 2 sets, lets say A and B. In a Venn Diagram that looks like 2 overlapping circles. A union B = A + B - (A intersect B) A intersect B is the region that both circles have in common. You subtract that because it has already been included when you added circle A, so you don't want to add that Again with circle B, thus you subtract after adding B. With three sets, A, B, C A union B union C = A + B - (A intersect B) + C - (A intersect C) - (B intersect C) + (A intersect B intersect C) You have to add the middle region (A intersect B intersect C) back because when you subtract A intersect C and B intersect C you are actually subtracting the very middle region Twice, and that's not accurate. This would be easier to explain if we could actually draw circles.
A quarter of a circle or a quadrant!
a circle
Concentric circles are a series of circles within each other.
Concentric circles are circles within other circles. Some examples of concentric circles are archery targets, the bullseye on a dart board, the eye, a wheel with a hubcap.
Then it could be a straight line segment within a quadrant

Concentric circles, are circles within circles. Each concentric circle on the surface of a disk represents a track, the narrower the circle is, the more data can be stored on the disk.
An angle in a quadrant refers to an angle formed by a ray that originates from the origin of a coordinate plane and lies within one of the four quadrants. Each quadrant is defined by the x-axis and y-axis, and angles in a quadrant are measured in a counterclockwise direction from the positive x-axis. The measure of an angle in a quadrant typically ranges from 0 degrees to 90 degrees.
To find the sin/cos at a given point on the unit circle, draw a radius to that point. Then break the radius into components - one completely horizontal and one completely vertical. The sine is the vertical component, the cosine is the horizontal component.
Circles indicate words contained within longer words and are usually related to the theme of the puzzle.
The four quadrants of the body are the right upper quadrant, left upper quadrant, right lower quadrant, and left lower quadrant. These quadrants are used to describe the location of organs within the abdominal area for medical and anatomical purposes.
