Answer:
Step-by-step explanation:
In order to solve this problem, one must use the trigonometric ratios. These ratios are the following,
Remember, each side is named relative to the angle, thus sides will attain different names depending on the angle which one sues to calculate with.
In this case, one is given the measure of the angle, and the measure of the side opposite to the angle. One is asked to find the measure of the side adjacent to the angle. Use the trigonometric ratio (
) to solve for the unknown. Substitute in the given values,
Manipulate the equation such that it is solved for the parameter(x),
Solve,
So, to find the find the amount of fencing required, or the circumference of the gardening, pot...
Area = pi * r^2
125 square feet = pi *r^2
125/ pi = r^2
39.79 = r^2
root square of 39.79 = r
6.31 = r
To find the circumference, the formula is: pi * D (or Pi * r * 2)
therefore,
C = pi * 6.31 *2
C = 39.65 feet
therefore, 39.65 feet of fencing is needed.
hope this helps
Answer:
C
Step-by-step explanation
This has a factor of 6% or 0.06. But, you are adding and not subtracting so it is 1.06. ( If you multiply by a number less than 1 then it is actually dividing) So C is the only on that is correct.
