A shape with no straight edges that can be described as looking like 'a squashed circle' is called an ellipse. This shape is also sometimes referred to as an oval.
No. Every circle on the sphere whose center is also the center of the sphere is a great circle. If the circle's center is not also the center of the sphere, then the circle is a small circle.
False.Every parallelogram is not a rhombus, but every rhombus is also a parallelogram.
An ellipse has just one. An oval can also refer to a circle that has been stretched by inserting two parallel straight sections - as in a running track. In such cases, it has two curved lines.
Yes, it is.
It is false
true
The base of a cone is always a circle. it also can be a ellipse.
No. It can also be a circle, ellipse or hyperbola.
A circle could be, and I think that an ellipse also could be.
A triangle. Also, any shape that has no corners, such as a circle or an ellipse.
An oval is a general word that could have different shapes. If you squash a circle evenly, the new shape in math is called an ellipse, which has an oval shape. The formula for the area of a circle is Pi times the Radius of the circle squared. The radius is half the height of the circle and also half the width of the circle. The general formula for the area of an ellipse is Pi times half the height times half the width. So we say length A is half the height of an ellipse and length B is half the width of an ellipse. When A is equal to B you have a circle. When they are different you have an ellipse. So if you want the area of the circle to be the same as the area of the ellipse, then you have to keep the height times the width the same for the ellipse as it was for the circle. As you squash the ellipse further the width must stretch out more than the height gets pushed down. For example, a circle with radius of 1 inch would have the same area as an ellipse with height ½ inch and width 2 inches because 1 times 1 is equal to ½ times 2. Another ellipse with the same area could have height ¼ inch and width 4 inches.
An ellipse with less eccentricity will be closer in shape to a circle, so it will generally be smaller than an ellipse with more eccentricity which is more elongated. The size comparison also depends on the specific dimensions of the ellipses.
A randomly deformed circle has no specific name. A circle can be deformed into an ellipse (also known as an oval). An ellipse has two distinct "centres", called foci. The shape consists of the locus of points such that the sum of the distance from these points to the two foci is a constant.
A : A circle is a closed figure with eccentricity 1. Similarly, ellipse is also a closed fig with eccentricity less than 1 and parabola with greater than 1.
The planets orbit in an ellipse. An ellipse is described as a geometric shape where the sum of the distance from the foci at any point is the same. An ellipse has three main points. Two foci and a center like a circle. While a true circle has all its external points equidistant from its center, an ellipse measures its points from the foci, which are equidistant to the center point at on both sides. The planets ellipse is closer to a circle than an all out ellipse, however, the orbit is still a true ellipse. It is also true that the shape of a planet's orbit (an ellipse) is a conic section, i.e. the intersection of a right circular cone where the intersecting plane is not perpendicular to the cone's axis, but less than being parallel to one of the cone's nappes.
This is not possible, since the point (4,6) lies inside the circle : X2 + Y2 = 16 Tangents to a circle or ellipse never pass through the circle
