What is a hexagonal pyramid?

Back

A hexagonal pyramid is a three-dimensional geometric shape with a hexagonal base and six triangular faces that converge at a single point called the apex.

Front

What shape is the vertical cross-section of a cylinder?

Back

The vertical cross-section of a cylinder is a rectangle.

Front

What 3D solid is formed by rotating a circle around an axis?

Back

A sphere is formed by rotating a circle around an axis.

Front

What is the definition of a cylinder in 3D modeling?

Back

A cylinder is a three-dimensional shape with two parallel circular bases connected by a curved surface.

Front

Describe the cross-section of a cylinder.

Back

The cross-section of a cylinder is a rectangle when cut vertically and a circle when cut horizontally.

Front

What is the difference between a prism and a pyramid?

Back

A prism has two parallel bases that are congruent polygons, while a pyramid has one base and triangular faces that meet at a single apex.

Front

What is the formula for the volume of a cylinder?

Back

The volume of a cylinder is calculated using the formula V = πr²h, where r is the radius of the base and h is the height.

Front

What is a sphere?

Back

A sphere is a perfectly round three-dimensional shape where every point on the surface is equidistant from the center.

Front

What is the lateral surface area of a cylinder?

Back

The lateral surface area of a cylinder is calculated using the formula A = 2πrh, where r is the radius and h is the height.

Front

What is the relationship between the radius and diameter of a circle?

Back

The diameter of a circle is twice the length of the radius (D = 2r).
