The dimensions of this cube are height (h) = 1, length (l) = 6, and width (w) = 1. What is the volume?
| 36 | |
| 96 | |
| 60 | |
| 6 |
The volume of a cube is height x length x width:
v = h x l x w
v = 1 x 6 x 1
v = 6
The formula for the area of a circle is which of the following?
a = π r |
|
a = π d |
|
a = π d2 |
|
a = π r2 |
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.
