Answer:

16π square centimeters.

Step-by-step explanation:

The area of a circle is πr².

Here, we are given the diameter, but we just need to divide it by 2 to get the radius.

8/2 = 4

So, the radius is 4 cm.

Now, we can substitute it into the formula to find the area.

π x 4²

π x 16

16π

So, the area of this circle is 16π.

Which is the graph of the system of equations?<br> x + 2y = 2<br> 4x - y = 4
Sladkaya [172]
Solve for x for x: x+2y=2
x+2y +-2y=2+-2y (add -2y on both sides.)
x=-2y+2
Substitute : -2y+2 for x in
4x-y=4:
4(-2y+2)-y=4
-9y+8=4 Simplify both sides of the equation.
-9y+8+-8=4+-8 Add -8 to both sides.
-9y=-4
-9/-9=-4-9 Divide both sides by -9
y=4/9
Substitute 4/9 for y in
x=-2y+2
x=-2(4/9)+2
x=10/9
y=4/9,x=10/9
