We are asked to calculate the circumference of the two circles; all the required information is given to us.
- The formula for the circumference is: .
'
In this formula,
------------------------------------------
Question #1
------------------------------------------
<u>Circumference of Circle</u>
<u></u>
<h3>Given value(s):</h3>
So to solve for circumference, we should substitute 10 for y, which gives us:
Circumference:
------------------------------------
Question #2
-------------------------------------
This time, the diameter is 6 units. We follow the same steps to find the circumference:
Upon multiplication,
Hope it helps you out! :)

Answer: D
(5/4) (1/6) 4^ (5/6)
Step-by-step explanation: I’m taking the test for this unit and I got it wrong but this was the CORRECT answer.
Answer:
(x,y) (9,4)
Step-by-step explanation:
-2x+7y = 10
x -3y = -3 (move x to the other side)
-2x +7y = 10
x = -3 + 3y (put in for x)
-2 (-3 +3y) +7y =10 ( slove for y)
6-6y +7y = 10
6+y = 10
y = 10-6
y = 4
go back slove for x
x = -3+3x4
x = 9
The answer would be the bottom left one because 5.15 round to 5 and 42,980 rounds to 40,000 which is equal to 4x10^4 (4 zeros). Then you subtract the exponents and divide the other terms to get 1.25x10^2
