Circle Questions and Answers (Q&A)

The circumference is the measurement of a circle. There are different reasons why you may need to calculate the circumference of a circle in real life. If you wanted to know the area of a pizza besides knowing that it is small, medium or large, also, the pizza might say that it is nine inches. However, this measures the inches around the pizza and not the whole amount of inches on the inside of the pizza.

Therefore, you will need to know the circumference of it. To do that, you will need to know the diameter or radius of the circle. Then use the formula C = 2 (3.14) (r). Therefore if you plug in the numbers, you would get 314 inches.

A circle is a figure, and a two-dimensional sphere is a three-dimensional object. One can only calculate the surface of a circle, whereas it is possible to calculate the volume of a sphere. A circle is a basic closed curve, which divides the plane into two regions.

Asphere is a round, solid character by its surface, and every point on its surface is away from the center. A circle is a shape with all positions at the surface, equal distance from the sphere. Some common examples of a circle include bangles and tires. Common examples of a sphere include tennis balls and planets. A sphere has a larger volume but a smaller surface area.

Circle and eclipse are mostly discussed in mathematics, and they usually come with problems that are technical most times. However, there are some differences between the circle and the eclipse. A ring is a two-dimensional geometric figure, a line, consisting of the set of all those points in a plane that are equally distant from another point. All the points in a circle equidistant from the center of the circle. This means they must have equal value when you measure the distance between each point from the center of the circle. A circle also has a diameter that divides the circle into two. Any line linking the center of a circle with any part of the circumference is called Radius. Eclipse, on the other hand, is when the plane cuts through the axis of a cone in an orthogonally way. Unlike the circle where all the points are equidistant, points in eclipse are not equidistant from the center of the circle

Perpendicular drawn from centre of chord bisects the chord hence am = md
also bm=mc
subtracting
ab=cd
hence cd=10cm

Wrong very wrong!!! None of the above. bc, try substituting the point a and b to equation 1 and 3

The area of a circle is also called the circumference. Circles are unique in that they do not have any number of sides like most other shapes do. When finding the area of a circle you must use the formula Pi times radius squared. Pi is the ratio of a cicrle's circumference to its diameter. Pi is a long series ofnumbers beginning with 3.1415.

The radius of a circle can be found by finding the distance between the center of a circle and its outer edge. It may seem a bit more complex to deal with finding the area of a circle vs. other three or four sided shapes but when you get the hang of it you'll find its simple and easy.
