An equation is two expressions separated by an equal sign. The key to solving equations is to repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.
The dimensions of this cylinder are height (h) = 3 and radius (r) = 3. What is the volume?
| 12π | |
| 16π | |
| 27π | |
| 96π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(32 x 3)
v = 27π
If a = c = 9, b = d = 4, what is the area of this rectangle?
| 12 | |
| 2 | |
| 36 | |
| 40 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 9 x 4
a = 36
