Actually Welcome to the Concept of the areas.
Since we know that, radius = diameter /2
here, => d = 2r ,
hence we use the formula as,
A = πr^2 ,
here option d.) is correct.

It is very important to look at all the details that are already given in the question. Only then the problem should be started for solving.
Initial population of Memphis = 350000
population of Memphis after 1 year = 406000
Then
Increase in population of Memphis in a year = 406000 - 350000
= 56000
Then
Percentage increase in the
population of Memphis in a year = (56000/350000) * 100
= (56 * 10)/35
= 560/35
= 16 percent
So there is a 16% increase in the population of Memphis in a year.
