Question 1169347
.
A city park has a circular goldfish pond with a diameter of 40 metres. Park officials want to surround the pool 
with a 100 centimetre-wide cement walk. Find the volume of cement needed for this project, to the nearest tenth of a cubic metre, 
if the layer of concrete is to be 20 centimetres deep
~~~~~~~~~~~~~~



For your info


<pre>
    Cement mass comprises only small fraction of the concrete mass.

    Therefore, the presented data is not enough to answer the problem's question.

Strictly saying, it is not a Math problem - - - it is a provocation, instead.


Or a very unprofessional formulation - - - of the two my statements choose whichever you like more.
