1.
C= 3.14 * 9
C= 28.26
The circumference is 28.3 cm......
2.
C=3.14 * (2*13)
C=3.14 * 26
C= 29.14
The circumference is 19.1 cm....
I don't know for sure but I know that based on seventh grade math that I know the line on the graph would look like a triangle not sure though
in plain and short, to graph an inequality, we first graph its EQUALITY graph, and then we do the shading.
so to graph y > x + 3, we first graph y = x + 3, which is just a line, and then do a true/false check on a point to see which side we shade.
let's hmmm check the point say (0,2), x = 0, y = 2.
y > x + 3
2 > 0 + 3
2 > 3 <--- is that true? is 2 really larger than 3? nope, so is false.
that simply means that the point (0, 2) is on the false area, so that's the area we do NOT shade, so <u>we shade the other side</u>.
y > x + 3, means "y" is greater than or larger than that line, but not equals, larger not equal, meaning the values on the borderline are not included, so the line is a dashed line.
check the picture below.
Answer:
b = 5√2, c = 10√3 is the right answer
You can factor the formula for the volume as

So, your solid could be a prism. Its base is a square with side
and height
.
So, its volume would be
