It's a pretty straightforward subtraction problem. As with any decimal addition or subtraction, you line up the decimal points and extend any numbers with zeros to make the number of decimal places match.
Answer:
<h2>The missing value is 3, and the coordinates are (3,3).</h2>
Step-by-step explanation:
The complete question is
Complete the missing value in the solution to the equation. (3, ? )
By given, we know that 
, because coordinates are written like 
.
Then, we replace the given coordinate to find 
.
Therefore, the missing value is 3, and the coordinates are (3,3).
Answer: So when you double the radius, the area goes up by 4 times because 2 squared is 4. The area will always go up by the square of how much the radius goes up. By contrast, the circumference will only double -- from 12.56 to 25.12 because you do not square the radius (or diameter) -- you just multiply it by pi.
12in.=1ft
so 240in./12in. = 20ft
