Geometry Mini-Lesson
Wheezer the Clown likes to play with balloons at
birthday parties. To make his entertainment more
exciting, he recently bought some spherical
balloons whose radii are double the radii of the
spherical balloons he used to use. How much more
breath will he need to blow up the new balloons?

1. Wheezer is going to need twice as much breath to
   blow up the new balloons.
2. Wheezer is going to need three times as much
   breath to blow up the new balloons.
3. Wheezer is in trouble he's going to need four
   times as much breath to blow up the new balloons.
   
4. Wheezer is really in trouble he's going to need
   eight times as much breath to blow up the new
   balloons.

Jasper has a soup can in the shape of a right
circular cylinder. The height of the soup can is
3 inches. He doubles the diameter of the soup
can. Which of the following statements is true?

1. The volume of the new soup can is two times the
   volume of the original can.
2. The volume of the new soup can is four times the
   volume of the original can.
3. The volume of the new soup can is six times the
   volume of the original can.
4. The volume of the new soup can is eight times the
   volume of the original can.

A theater is considering enlarging its current
square concession area to provide more display
area for products and room for employees to
assist customers. Plan A is to double the length
and increase the width by a factor of 1.5. Plan B
is to double the length and the width. Which
statement is TRUE?

1. Plan A would yield an area 2.5 times the current
   area.
2. Plan B would yield an area twice the current
   area.
3. Plan A would yield an area ¾ as large as Plan B.
4. Plan B would yield an area 1.5 times larger than
   Plan A.
