Answer:

11. What is the shape of the bases?

Bases can be a triangle, square, rectangle or any other polygon. The other faces of a prism are parallelograms or rectangles.

Side faces: Side faces are rectangles

Height: Height is a side edge

Surface Area: bh+2ls+lb

12. What is the name of this solid figure?

In geometry, a tetrahedron, also known as a triangular pyramid, is a polyhedron consisting of four triangular faces, six straight sides, and four vertex corners. The tetrahedron is the simplest of all ordinary convex polyhedra and the only one with fewer than 5 faces.

13. What is the circumference of the base?

The base of a cone is a circle. This means we can calculate its area using the formula multiplied by the radius squared and its circumference by multiplying two by by the radius.

14. What is the height of the cylinder?

The height of a cylinder of revolution is the length of the generating line segment. The line that the segment is revolved about is called the axis of the cylinder and it passes through

15. Lateral area = _ _ _ _ _base _ _ _ _ _ of the prism.

Lateral area = perimeter base height of the prism.

16. What is the area of the base?

The area of a base or rectangle is equal to its length, l, multiplied by its width, w: A = l x w. Given a pyramid whose base is 10 inches long and 15 inches wide, find area as follows: A = 10 inches x 15 inches = 150 square inches.

17. Surface area = _ _ _ _ _ area + _ _ _ _ _

17. Surface area = literal area + (2 × area of base).

18. The formula to find the surface area of a cylinder is _ _ _ _ _.

The formulas of cylinder are: Total surface area = 2πr(r+h) square units. Volume of cylinder = πr2h cubic units.

19. For this cylinder, the surface area is _ _ _ _ in

2.

The formula to calculate the total surface area of a cylinder is expressed as, total surface area of cylinder = 2πr(r + h). This total surface area includes the area of the 2 bases (2πr2) and the curved surface area (2πrh). Here 'r' is the radius and 'h' is the height of the cylinder.
