The dimensions of this cube are height (h) = 6, length (l) = 1, and width (w) = 5. What is the volume?
| 144 | |
| 30 | |
| 3 | |
| 64 |
The volume of a cube is height x length x width:
v = h x l x w
v = 6 x 1 x 5
v = 30
What is the circumference of a circle with a radius of 11?
| 15π | |
| 22π | |
| 12π | |
| 6π |
The formula for circumference is circle diameter x π. Circle diameter is 2 x radius:
c = πd
c = π(2 * r)
c = π(2 * 11)
c = 22π
The formula for the area of a circle is which of the following?
c = π d2 |
|
c = π r2 |
|
c = π r |
|
c = π d |
The circumference of a circle is the distance around its perimeter and equals π (approx. 3.14159) x diameter: c = π d. The area of a circle is π x (radius)2 : a = π r2.
If c = 3 and y = 6, what is the value of 2c(c - y)?
| 765 | |
| -459 | |
| -18 | |
| 55 |
To solve this equation, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
2c(c - y)
2(3)(3 - 6)
2(3)(-3)
(6)(-3)
-18
