x2 + y2 = r2
Where "x" and "y" represent the co-ordinates of any point on the curve relative to it's center point, and "r" represents it's radius. If you want to specify a curve that goes around a specific point (we'll call it {a, b}), then that can be expressed as:
(x - a)2 + (y - b)2 = r2
A good place to measure is the diameter of the circular end. That gives you the area of the circular end, and the only other number you need in order to calculate the cylinder's volume is its straight length.
If a right circular cone intersects a plane that runs perpendicular to the cone's axis but does not pass through its vertex the resulting curve will be a circle.

The given description fits that of a cone
An ellipse is a closed curve that is not circular (the curve is not a constant distance from any point inside of the curve). While some planetary orbits are relatively circular, others are more elliptical, that is having an oval shape with a varying distance from the Sun.

A cone.
Normally just 1 circular curve
A cylinder has two circular faces.

The circular orbit equation used to calculate the motion of objects in a circular path is called the centripetal force equation, which is F mv2/r.
If the curve is on the xy-plane, finding an expression for dy/dx will give you the slope of a curve at a point.
Curve linear is antonym to linear. Circular is one among many curvelinear motions. In case of circular there will be a constant radius but in curvelinear radius would change at every instant
a cylinder.it has 2 circular faces and curves around
