You have to do 3.14 times the diameter of the circle.
As we know Conversion from fahrenheit to celsius is

We can write it also as

F as y and C as x then we can write it as
Answer:
Step-by-step explanation:
12 - 12x = -6x + 48
Add 12x to both sides. That eliminates the x term on the left side.
12 = 6x + 48
Subtract 48 from both sides. That eliminates the constant term on the right side.
-36 = 6x
x = -6
Left to right. Whatever comes first (multiplication or division) you do. This is all part of the PEMDAS/Order of operations.
Hopefully I solved your problem! :)
<em><u>The average would be 16.</u></em>
To calculate this, add all the values together then divide that sum by the amount of data values.
11+16+15+22=64
64÷4=16
