A = 28.26 units^2
Step-by-step explanation:
The formula for the area of a circle is:

We can just plug in the numbers and solve.


28.26 units^2
Answer: Linear equations in two variables. If a, b, and r are real numbers (and if a and b are not both equal to 0) then ax+by = r is called a linear equation in two variables. (The “two variables” are the x and the y.) The numbers a and b are called the coefficients of the equation ax+by = r.
Step-by-step explanation:
The value is what the Y axis is when X is 8.
Draw a vertical line down from X=8 and see where the line crosses on the Y axis.
See the attached picture. The answer is Y = -4
9 7/8, 9 3/4, 9 1/4, 10, 10 5/8, 10 3/8, 10 1/8, 10 1/2
