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.
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.
What is the circular region of a circle?
the distance around a circular region is called circumference
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.
Which shape has one circular base?
A cone or a hemisphere or circle
Why are circles and cylinders alike?
The circular base of a cylinder has the same properties as that of a circle.
What happens when you slice a sphere with a plane?
The sphere forms a circle in the plane. There are two bits of sphere which are spherical caps with a circular base.
What is the shape of the intersection of a cylinder and a plane that is perpendicular to the circular base?
not quite a cirlcel but an oblong circle.
What is the shape of sides of a cone?
In a right circular cone the base is a circle and the sloped side is a sector of a circle. For a general cone, they are an ellipse and a sector of an ellipse.
How does the formula of the area of a circle relate to the volume of a cylinder?
The volume of a cylinder is its height times the area of its base. And the area of its base is the area of a circular shape.
What is the surface area of a right circular cylinder with base circle of radius of 5M and height of the cylinder 10M?
150
Why is circle called a circle?
it is called circle because it is circular. circular means smooth, rounded edges. a circle matches that description.
How do you find an experimental value of pi?
The ratio of C to D will equal pi. This is based on the known formula for the circumference of a circle. D = Diameter of the circular base of a cylinder (independent) C = Circumference of the circular base of a cylinder (dependent)
What does the net of a cone look like?
a circle base with the sides rising up in a circular fashion meeting at one point
Does a right circular conehave a triangular as a base?
The answer is "No"; a right circular cone has a circle as its base while a right triangular cone has a triangular base (which we usually call a "pyramid". The Egyptian Pyramids have square bases. And the volume of any "right" pyramid is found by multiplying the area of its base by its VERTICAL height.
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.
