Several geometric forms are closely related to the circle, including the sphere (a three-dimensional version of a circle), the ellipse (a stretched or compressed circle), and the cylinder (formed by extending a circle in a straight line). Additionally, the circle is a special case of an ellipse where the two foci coincide at the center. These forms share similar properties and equations related to their shapes and dimensions.

Oh, dude, you're talking about the circle's posse! So, the circle is tight with its homies like the sphere, the ellipse, and the parabola. They all roll together in the world of shapes, sharing the same mathematical DNA and keeping it real in geometry class.

The diameter of a circle is twice its radius.

The volume of a cylinder is the cross-sectional area of the cylinder multiplied by its length. The perpendicular cross-section of a cylinder is a circle.
Divide the diameter by 2 to get the radius. See related questions below.
