Select the correct answer. Eric needs to manufacture a turntable with a circumference of `140pi` centimeters. If the allowed error tolerance in the circumference is `+-5` centimeters, how close to the ideal radius must he control the radius of the turntable? A. `10/pi` B. `2/pi` C. `5/(2pi)` D. `5/(4pi)`

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

the answer is 99.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
