Draw a number line with 10 positives and 10 negatives. Count from 0 to 8. Now, from 8, count back 12 spots. From that spot, go back to 0, which is their original position. The number you counted there is your answer.

The answer is A because the dependent quality is on the y-axis
Area of a circle is:
A = pi * r^2
If the diameter is 10 feet, the radius will be half of that or 5.
So:
A = 3.14 * 5^2
Simplify exponent:
A = 3.14 * 25
Multiply:
A = 78.5
