Area and Volume Formula Answers

 

1.

TSAright circular cyl.

2.

fake formula (LSA of a double cone?)

3.

TSAhemisphere

4.

TSAsphere

5.

Vsphere

6.

TSAright circular cone

7.

LSAright circular cyl.

8.

Atriangle

9.

Akite (also works for any other quadrilateral having perpendicular diagonals)

10.

Asquare

11.

Aequilat. triangle

12.

Atriangle (also useful for isosceles triangles, since h is usually easy to compute with Pythagorean Thm.)

13.

Aparallelogram (obviously works for rhombus, square, or rectangle, too)

14.

Vprism (any prism, not only right prisms)

15.

Vpyramid (any pyramid, not only right pyramids)

16.

Acircle

17.

Vcircular cyl. (does not have to be right)

18.

Vcircular cone (does not have to be right)

19.

LSAright circular cone

20.

TSAcylindrical cup

21.

Atrapezoid

22.

Atrapezoid again (where M = median)

23.

nothing special (fake formula)

24.

nothing special (could be the curved area of half a cylinder, but the LSA of half a cylinder would have to include 2rh for the area of the rectangular side)
