How are a sphere and a cone alike and different?
Spheres are spherical, with no base, and have no flat surfaces. Cones have a flat, circular base, with a circular altitude protruding from the edges of the circle. The altitude's diameter slowly diminishes until all edges reach eachother.
What is the circular region of a circle?
the distance around a circular region is called circumference
The volume of a right circular cone of altitude h and base r?
A right circular cone with altitude h and base r is equal to (1/3)*pi*r2*h. This is one third of the volume of a right cylinder with the same dimensions, and can be written as (1/3)*A*h where A is the area of the base circle.
How many faces does a circle based pyramid have?
A circle-based pyramid, also known as a cone, has two faces: the circular base and the curved surface that tapers to a point at the apex. The base is a flat, two-dimensional shape, while the curved surface is a three-dimensional shape that extends from the base to the apex. Therefore, a circle-based pyramid has a total of two faces.
What has a circular base and a vertex that isn't in the same plane as the base?
A shape with a circular base and a vertex that isn't in the same plane as the base is called a cone.
