Example Questions

Example Question #271 : Ssat Upper Level Quantitative (Math)

If you have a circular yard and need to put up a fence around the outside, you would use the formula  to figure out the amount of fence you need.

Possible Answers:

True

False

Correct answer:

False

Explanation:

To figure out the amount of the fence around a circular yard, you need to find the circumference of the yard.  The equation for the circumference of a cirle is  and not .

Example Question #272 : Ssat Upper Level Quantitative (Math)

Find the circumference of a circle with a diameter of 12.

Possible Answers:

Correct answer:

Explanation:

There are two possible formulas for finding the circumference of a circle. They are as follows:

And:

Where C is circumference, r is radius, and d is diameter.

For this problem, we are given the diameter is 12, meaning we can plug our numbers into the second equation. Since pi is an irrational constant, it is okay to leave the answer in terms of pi.

Example Question #273 : Ssat Upper Level Quantitative (Math)

Find the circumference of a circle with a diameter of 6.

Possible Answers:

Correct answer:

Explanation:

There are two possible formulas for finding the circumference of a circle. They are as follows:

And:

Where C is circumference, r is radius, and d is diameter.

For this problem, we are given the diameter is 6, meaning we can plug our numbers into the second equation. Since pi is an irrational constant, it is okay to leave the answer in terms of pi.

Example Question #51 : Geometry

Find the circumference of a circle with a diameter of 2.

Possible Answers:

Correct answer:

Explanation:

There are two possible formulas for finding the circumference of a circle. They are as follows:

And:

Where C is circumference, r is radius, and d is diameter.

For this problem, we are given the diameter is 2, meaning we can plug our numbers into the second equation. Since pi is an irrational constant, it is okay to leave the answer in terms of pi.

Explanation:

There are two possible formulas for finding the circumference of a circle. They are as follows:

And:

Where C is circumference, r is radius, and d is diameter.

For this problem, we are given the radius is 27, meaning we can plug our numbers into the first equation. Since pi is an irrational constant, it is okay to leave the answer in terms of pi.

Example Question #2 : How To Find The Equation Of A Line

Given the graph of the line below, find the equation of the line.

 

Act_math_160_04

Possible Answers:

Correct answer:

Explanation:

To solve this question, you could use two points such as (1.2,0) and (0,-4) to calculate the slope which is 10/3 and then read the y-intercept off the graph, which is -4.

 

Example Question #2 : Coordinate Geometry

Which line passes through the points (0, 6) and (4, 0)?

Possible Answers:

y = 2/3x –6

y = 2/3 + 5

y = 1/5x + 3

y = –3/2 – 3

y = –3/2x + 6

Correct answer:

y = –3/2x + 6

Explanation:

P1 (0, 6) and P2 (4, 0)

First, calculate the slope:  m = rise ÷ run = (y2 – y1)/(x– x1), so m = –3/2

Second, plug the slope and one point into the slope-intercept formula: 

y = mx + b, so 0 = –3/2(4) + b and b = 6

Thus, y = –3/2x + 6

Example Question #3 : Coordinate Geometry

What line goes through the points (1, 3) and (3, 6)?

Possible Answers:

–3x + 2y = 3

2x – 3y = 5

4x – 5y = 4

–2x + 2y = 3

3x + 5y = 2

Correct answer:

–3x + 2y = 3

Explanation:

If P1(1, 3) and P2(3, 6), then calculate the slope by m = rise/run = (y2 – y1)/(x2 – x1) = 3/2

Use the slope and one point to calculate the intercept using y = mx + b

Then convert the slope-intercept form into standard form.
