To solve for r, we are going to want to get it on one side of the equation by itself, or isolate it. To do this, we can divide both sides of our equation by π, as shown below:

C = \pi r

\dfrac{C}{\pi} = \dfrac{\pi r}{\pi}

\boxed{\dfrac{C}{\pi} = r}


We can see that r = C/pi.

\pi r=C\ \ \ |:\pi\\\\\boxed{r=\dfrac{C}{\pi}}

hmmm... Correct formula of circumference of a circle is

C=2\pi r\ \ \ |:2\pi\\\\\boxed{r=\dfrac{C}{2\pi}}

Which graph has the same end behavior as the graph of f(x) = –3x^3 – x^2 + 1?
ololo11 [35]
To find out end behavior, we always look at the largest exponent (3 in this case) and the sign of the term with the largest exponent (negative in this case). We can rule out the first two choices because since it is a cubic graph (exponent of 3) the graph will be pointing in opposite directions. Then, the negative tells us that as the x values approache infinity, the y values will approach negative infinity. So the correct answer is the last choice.

Hope this helps

How do you round 38,288 to the nearest 100
lys-0071 [83]

Consider the number 38,288

Now, we have to round this number to the nearest hundreds place.

The place value to the extreme right of the number is ones, then tens, hundreds, thousands, ten thousands and so on.

So, the digit at hundreds place = 2

Consider the digit to the right of the hundred place which is '8', which is greater than 5.

Therefore, we will add '1' to the digit at hundreds place.

Therefore, the number 38,288 rounded to nearest hundreds is 38,300.
