Answer:
Using 3.14 as pi, the answer would be 56.52, and using just pi (as in the input on a calculator) would be 56.54867.
Step-by-step explanation:
The equation for circumference of a circle is C = πd, C representing the circumference and d representing the diameter. Since the equation shows the radius, the equation can also be C = 2πr, since the radius is half of the diameter. Multiply nine by two to get eighteen. 18 times 3.14 = 56.52.
Basically it’s like 40x10 and then let’s say your exponent is two so you would do that equation twice so it would be 800
Answer:
A line segment has two endpoints. It contains these endpoints and all the points of the line between them. You can measure the length of a segment, but not of a line. Line segments are only a line that goes from one point to another, and lines go on forever. However, a line segment is also part of a line.
Hope this helps!
Answer:
x = -1
y = 3
Step-by-step explanation:
Add the two equations together.
You get:
4x = -4
You may notice that there is no <em>y</em>, and that is because the y's cancel out. -y + y = 0, so there's no use in putting <em>y </em>in.
x = -1.
Plugging x in, we get:
-1 - 2y = -7.
Move the -7 over to the left side.
6 = 2y
Therefore, y = 3.
We can check our answer by plugging the values in.
3(-1) + 2(3) is supposed to equal 3.
-3 + 6 = 3, and so we know our answer is correct.
