The first step in solving this is to substitute x with 3 and y with 2, so that

becomes

Then simply solve using the order of operations.
First exponents (there are no parentheses)

Then multiply and divide

And finally add and subtract

Therefore the value <span>of 1/3 x^2 + 5.2y when x=3 and y=2 is 13.4</span>

I recommend that you download photomath, it is an app that takes a photo of the equation and answers it most of the time.
The circle increase in area will be by a factor of 1.5
So corresponding increase in the diameter will be a factor of sqrt 1.5 = 1.2247
Answer is 22.47 %
