Chapter 12.2: Surface Area of Prisms and Cylinders

Question 1

Prism

Answer 1

a polyhedron that has two parallel, congruent faces called bases.

Question 2

Altitude/Height

Answer 2

the perpendicular distance between its bases.

Question 3

Right Prism

Answer 3

each lateral edge is perpendicular to both bases.

Question 4

Surface Area

Answer 4

the sum of the areas of its faces.

Question 5

Thm. 12.2 - Surface Area of a Right Prism

Answer 5

the surface area, S, of a right prism is S=2B + Ph where B is the area of a base, P is the perimeter of a base, and h is the height.

Question 6

Circular Cylinder

Answer 6

a solid with congruent circular bases that lie in parallel planes.

Question 7

Right Cylinder

Answer 7

a cylinder is right if the segment joining the centers of its bases is perpendicular to its bases.

Question 8

Thm. 12.3 - Surface Area of a Right Cylinder

Answer 8

the surface area, S, of a right cylinder is S=2B + Ch = 2 x3.14 r2 + 2 x 3.14 r h where B is the area of a base, C is the circumference of a base, r is the radius of a base, and h is the height.
