1: Identify the lateral area and surface area of a right cone with radius 7 cm and slant height 15 cm.
L = 659.7 cm2 ; S = 483.8 cm2
L = 329.9 cm2 ; S = 373.9 cm2
L = 659.7 cm2 ; S = 813.6 cm2
L = 329.9 cm2 ; S = 483.8 cm2

2: A right cone has radius 5 ft and slant height 9 ft. The radius and slant height are both multiplied by 1/2. Which of the following correctly describes the effect on the surface area?

The surface area is multiplied by 1/4.
The surface area is multiplied by 1/2.
The surface area is multiplied by 2.
The surface area is multiplied by 4.

2: A regular pentagonal prism has a height of 12 in. and base edge length of 8 in. Identify its lateral area and surface area.

L = 480 in2 ; S = 590.1 in2
L = 576 in2 ; S = 590.1 in2
L = 576 in2 ; S = 700.2 in2
L = 480 in2 ; S = 700.2 in2

4: Identify the lateral area and the surface area of a right rectangular prism with a 12 cm by 10 cm base and height 16 cm.

L = 704 cm2 ; S = 944 cm2
L = 352 cm2 ; S = 824 cm2
L = 352 cm2 ; S = 944 cm2
L = 704 cm2 ; S = 824 cm2

5: A right rectangular prism has length 9 cm, width 5 cm, and height 3 cm. If the length, width, and height are doubled, what happens to the surface area?

The surface area is multiplied by 6.
The surface area is multiplied by 4.
The surface area is doubled.
The surface area is multiplied by 8.

I know this is a lot.. but i am stumped. PLS HELP
