If the base of this triangle is 9 and the height is 9, what is the area?
| 40\(\frac{1}{2}\) | |
| 38\(\frac{1}{2}\) | |
| 48 | |
| 30 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 9 x 9 = \( \frac{81}{2} \) = 40\(\frac{1}{2}\)

A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
On this circle, a line segment connecting point A to point D is called:
circumference |
|
chord |
|
radius |
|
diameter |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
What is the area of a circle with a radius of 5?
| 16π | |
| 9π | |
| 7π | |
| 25π |
The formula for area is πr2:
a = πr2
a = π(52)
a = 25π
The dimensions of this cylinder are height (h) = 3 and radius (r) = 4. What is the volume?
| 4π | |
| 32π | |
| 5π | |
| 48π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(42 x 3)
v = 48π
