The answer would be 153.94cm
Formula for the area of a circle is A=pi*r^2
Pi=3.14
R=14/2=7
A=3.14*7^2
A=153.94cm
Solution: Which statement about the scatter plot is true?
The correct answer is option A. As the number of weeks in class increases, the number of keyboarding mistakes decreases.
Explanation: From the scatter plot, we clearly see there exists a negative linear relationship between the number of weeks in class and the number of mistakes. And we know that if there exists a negative linear relationship between the two variables, then the values of two variables move in opposite direction. If the values of one variable goes up, the values of other variable go down. From the given scatter plot, we clearly see the number of mistakes goes down as the number of weeks in class increases. Therefore, the option A is correct
Algebraic expressions are combinations of variables , numbers, and at least one arithmetic operation. For example, 2x+4y−9 is an algebraic expression. Term: Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables.

Livia eats a chicken drumstick with 11 grams of protein. She also eats x cheese sticks, each with 7 grams of protein. The table shows y , the total number of grams of protein that Livia will consume if she eats x cheese sticks. Livia may eat only part of a cheese stick, so x may not always be a whole number.
What is the range of the function?
Answer:
Step-by-step explanation:
Ax+By=C (remember this formula)
-2/9x+2=y (switched sides to make it easier)
-2x/9+2-y=0 ( put y on the other side)
-2x/9-y=-2 ( put 2 on the other side)
So a must be positive so multiply by -1
2x/9+y=2
answer
2x+9y=18 (LCM)
