Example Questions

Example Question #1 : Geometry

What is the area of the circle provided? 


6

Possible Answers:

\(\displaystyle 1\textup,024\pi\textup{ in}^2\)

\(\displaystyle 1\textup,023\pi\textup{ in}^2\)

\(\displaystyle 1\textup,025\pi\textup{ in}^2\)

\(\displaystyle 1\textup,026\pi\textup{ in}^2\)

Correct answer:

\(\displaystyle 1\textup,024\pi\textup{ in}^2\)

Explanation:

In order to solve this problem, we need to recall the formula for the area of a circle: 

\(\displaystyle A= r^2\pi\)

The circle in this question provides us with the radius, so we can use the formula to solve:

\(\displaystyle A=32^2\pi\)

Solve:

\(\displaystyle A=1\textup,024\pi\textup{ in}^2\)

Example Question #2 : Geometry

The figure represents a set of complementary angles, solve for \(\displaystyle x\).


4

Possible Answers:

\(\displaystyle 71^\circ\)

\(\displaystyle 69^\circ\)

\(\displaystyle 70^\circ\)

\(\displaystyle 68^\circ\)

Correct answer:

\(\displaystyle 70^\circ\)

Explanation:

Complementary angles are defined as two angles that when added together equal \(\displaystyle 90^\circ\)

From the question, we know that the two angles are complimentary, and thus equal \(\displaystyle 90^\circ\), so we can set up the following equation:

\(\displaystyle x+20=90\)

Next we can solve for \(\displaystyle x\):

\(\displaystyle \frac{\begin{array}[b]{r}x+20=90\\ -20-20\end{array}}{x= 70}\)

Example Question #3 : Geometry

Calculate the volume of the provided figure.


8

Possible Answers:

\(\displaystyle 214\textup{ in}^3\)

\(\displaystyle 216\textup{ in}^3\)

\(\displaystyle 215\textup{ in}^3\)

\(\displaystyle 213\textup{ in}^3\)

Correct answer:

\(\displaystyle 216\textup{ in}^3\)

Explanation:

In order to solve this problem, we need to recall the volume formula for a cube:

\(\displaystyle V=l\times w\times h\)

Now that we have the correct formula, we can substitute in our known values and solve: 

\(\displaystyle V=6\times6\times6\)

\(\displaystyle V=216\textup{ in}^3\)
