• 18.3 m
• 3.5 m
• 7.2 m

A box is shaped like a rectangular prism.  There are two sizes.  The larger box has dimensions that are three times the size of the original box.  What is the effect on the volume from the smaller to the larger box?

• The volume of the larger box is 3 times larger.
• The volume of the larger box is 9 times larger.
• The volume of the larger box is 27 times larger.
• The volume of the larger box is 27 times smaller.

Which ratio would you use to find the length of the side labeled c?

• sin 39 = 6/c
• sin 39 = c/6
• cos 39 = 6/c
• cos 39 = c/6

You have a right triangle with a base of 8 and a height of 10.  If the base is along the x-axis and the height is along the y-axis, what solid figure would you create if you rotate the triangle 360 degrees?

Write the equation of the circle on the graph.

• (x + 2)^2 + (y - 5)^2 = 9
• (x - 2)^2 + (y + 5)^2 = 9
• (x - 2)^2 - (y + 5)^2 = 9
• (x + 2)^2 - (y - 5)^2 = 9
