What is the area of a circle with a radius of 3?
| 81π | |
| 25π | |
| 7π | |
| 9π |
The formula for area is πr2:
a = πr2
a = π(32)
a = 9π
Solve for c:
c2 - 3c - 18 = 0
| 7 or 4 | |
| 3 or -7 | |
| -3 or -9 | |
| -3 or 6 |
The first step to solve a quadratic equation that's set to zero is to factor the quadratic equation:
c2 - 3c - 18 = 0
(c + 3)(c - 6) = 0
For this expression to be true, the left side of the expression must equal zero. Therefore, either (c + 3) or (c - 6) must equal zero:
If (c + 3) = 0, c must equal -3
If (c - 6) = 0, c must equal 6
So the solution is that c = -3 or 6
The dimensions of this cube are height (h) = 4, length (l) = 6, and width (w) = 9. What is the volume?
| 6 | |
| 10 | |
| 9 | |
| 216 |
The volume of a cube is height x length x width:
v = h x l x w
v = 4 x 6 x 9
v = 216
