Hi there
my question is
a city is laid out in the shape of a circle with a radius of 10 km.
there is a motorway that runs from east to west of the city along the centre.
The population density at a distance y km North or South is given by the function (D)= 4y
(so most people tend to live away from the motorway).
What is the total population of the city(or how would u find it)?
Thanks a lot
