What does circle have to do with math?
Circle is a shape. We have gotten to know a lot from circles. Because of circles, we get PI, radius, diameter, circumference, and other things. Circles fall into geometry, which is math. We can make many mathematical equations from circles.
How do you calculate area in math?
Squares: Take two sides and multiply them against each other, ex. 3.5•3.5= the area. Rectangles: Same as squares. A square is a rectangle. Circles: Radius times radius times pi equals area.
What tool is used to draw circles and arcs?
The tool commonly used to draw circles and arcs is called a **compass**. Here are some details about it: **Compass**: This is a drawing instrument that consists of two legs, one with a pointed end to anchor the tool at the center of the circle or arc, and the other with a pencil or pen to draw the circle or arc. The distance between the legs can be adjusted to change the radius of the circle or arc being drawn. Additionally, for more precise or larger scale drawings, other tools and devices might be used: **Beam Compass**: Used for drawing larger circles or arcs, it has a beam or rod with a sliding holder for the pencil or pen. **Protractor**: While not used to draw circles, a protractor is often used to measure angles and can assist in the construction of arcs. **Drafting Tools and Software**: In technical drawing and CAD (computer-aided design), software tools can be used to create precise circles and arcs digitally.
What is it called when a line goes halfway across a circle?
The radius of a circle is one half of the circle's diameter, any line going from the center of the circle to the circle itself. A line connecting other points on a circle (or on any curve) is called a chord.
Segment that has one endpiont at the center and the other endpoint on the circle?
A radius of a circle is a line segment joining the center of the circle to a point on the circle. All such segments have the same length, and this length also called the radius of the circle.
If two circles have the same center one with a 3 centimeter radius the other with a 1 centimeter radius What is the equidistant from the two circles?
If you create third circle with radius 2, then all the points on that circle would be equidistant form both circles. So the answer is a circle with radius 2.
Do concentric circles have the same circles?
No. You can only define a circle by radius, diameter, area, perimeter. Concentric circles have the same centre, therefore, if they were the same circles with the same radius, then they would all lie on top of each other and be effectively one circle.
Is concentric circle and congruent circle are they same?
No. Concentric circles have the same centre but not [usually] the same radius. Congruent circles have the same radius, but not [usually] the same centre. If you have two concentric congruent circles one will be exactly on top of the other.
What shape is formed when circles with the same radius are stacked on top of each other?
A cylinder.
What is the name of a line drawn from one side of a circle to the other through the center?
This is called the diameter of the line that passes through the center of the circle. Half of that line is called the radius.
What does circle have to do with math?
Circle is a shape. We have gotten to know a lot from circles. Because of circles, we get PI, radius, diameter, circumference, and other things. Circles fall into geometry, which is math. We can make many mathematical equations from circles.
What parallels are not circles?
If two circles are drawn using the same centre, the two lines of the circles are parallel as they don't meet each other.Two straight lines (think of railway tracks) are drawn next to each other, but never meet, they are parallel lines.
Is the center of a circle the point of intersection for two concentric circles?
Concentric circles are the circles with the same center therefore they do not cross with each other as the "center is not considered a point on the circle". An exception would be two circles that are concentric and have the same radius, in which case the circles are indistinct and every point of the circles is an intersection.
How many tangents can be drawn on three circles if they dont lie within each other?
if you mean common tangents there can be only 2 tangents
What is Venus' diameter radius circumference and area?
Venus' radius is 6052 kilometers. You can derive the other measurements by using the standard formulae for circles and spheres (and assuming that Venus is spherical, which is a fairly good approximation).
What is the circumference of a circle if the radius is 27 inches?
The circumference of a circle if the radius is 27 inches is: about 169.6 inches. (you can do this type of calculation for other circles using this formula: r x 2 x Pi = circumference).
How do you write an expression to find differences in areas of a circle?
Difference in areas = A1 - A2 where A1 and A2 are the areas of the larger and smaller circles. Other expressions will depend on what information about the circles is available: radius, diameter, circumference.
