Answer:
r = 85.625 units
Step-by-step explanation:
This question is apparently designed to cause trouble.
C = 2πr . . . . . formula for circumference
r = C/(2π) . . . . solved for radius
r = 269/π . . . . with the value of C put in
If you use an appropriately precise value for π, you get the answer shown above, 85.625. Here, "appropriately precise" means accurate to at least 5 digits. The value of π that gives the above result is 3.1416, accurate to 5 digits.
If you use a value of π accurate to only 3 digits, 3.14, the radius you obtain is 85.669. That 5-digit result cannot be relied upon when it is obtained using a 3-digit value for π. Unfortunately, many math problems (incorrectly) require the use of 3.14 for π, even when calculating results to 5 or 6 or 7 digits. In view of previous teaching, one cannot blame a student for making this selection.

The choice r=86.259 uses a value of about 3.1185 for pi. That is not even close to any value that is ever recommended for use in a problem like this.

The answer is: <span>A=<span>√265</span></span>.
A. first total salary (S) is what is being found so put that on one side of the equal side, then 100 dollars are being made and this is not changed so we don't need a variable, put that on the other side of the equal sign. and since sales (X) is changing, keep the variable, 30% of that is added to the salary, so multiply that by x (first turn it into a decimal, divide it by 100) and add that to the initial 100
S=100+.3X
B. do the same thing above but with a new decimal and initial salary
S=150+.15X
C. since they both need to be equal (S=S) you can replace the S on one equation with the other
100+.3X=150+.15X
Answer: B.) 1,500,000 centimeters
Step-by-step explanation: I took the test on it! a little hint, If you would've just looked up " Convert 15,000 meters to Centimetres. " The answer would've shown up with the accurate calculator that google has provided! Hope that helps luv <3
