Answer:
15
Step-by-step explanation:
Ok so first you need to know how to calculate the volume of a cylinder
I will put the formula here: V=πr2h
Since pi is equal to 3.14 as said in the problem we can simply divide 282.6 by pi, the radius and 2
That is equal to 282.6/3.14*3*2
A little calculation shows that, the answer is 15
Hope this helps :)
Data:
Formula: diameter = 2*radius
Formula: (<span>Circle length)
</span>

<span>
Solving: </span><span>Using the data
</span>diameter = 2*radius
20 = 2*r
2r = 20


<span>Now, replace in the circumference length formula
</span>



Answer:
<span>
The exact circumference of the circle is </span>

Ok, this is just like the systems of equations.
x-7 = 5x-31
Solve
x-7 = 5x-31
-x -x
-7 = 4x -31
+31 +31
24 = 4x
24/ 4 = 4x/ 4
x=6
