Question

A cone is a solid with base that is a ____, a point not in the same plane as the base, and all the points between them.

A. square
B. triangle
C. disc
D. rectangle​

Answer 1

C. disc

Explanation:

A cone is a 3-D solid shape with a flat circular base.

Parts of a Cone

The base of a cone is a flat disc that tapers down to a point. The tip of the cone is known as the vertex or the apex. The distance from the vertex to the center of the base is the height of the cone. Just like a circle, the distance from the center of the base to the edge is called the radius. Finally, the distance from the apex, along the edge of the cone, to the edge of the base is the length.

Cone Volume

The most common measurement of a cone is its volume. Since it's a 3-D shape, we can take the volume of the cone. Remember that volume describes the amount of space a shape takes up. The volume formula for a cone is:

• 
  `V=\pi r^2(h)/(3)`

In this formula, π is pi, r is the radius, and h is the height.
