Question 1114729
.
<pre>
1.  <U>Answer</U>.  {{{(pi*1000)/(pi*2)}}} = {{{1000/2}}} = 500 times.


2.  <U>Answer</U>.  {{{0.06*pi*8}}} = {{{0.06*3.14*8}}} = 1.51 millimeter (aproximately).




    To solve the problems, you need to know 


        a)  Circumference of the circle = {{{pi*D}}}, where {{{pi}}} = 3.14 and D is the diameter.


        b)  1%  is  0.01  of the value;  6% = 0.06 of the value.
