Increase=5%of 4
=5÷100×4=0.2
So 4+0.2=4.2litres

I thought this would be easy lol, I tried, sorry for not getting an answer
Answer:
Step-by-step explanation:
Amplitude is twice the coefficent of the sine function. In this case, 
Period is
divided by the coefficent of x, in this case, 
Phase shift, is how much you sum or subctract from x inside the sine, in this case
.
Midline you get by hiding the sine and reading what's left, in this case, -4.
The graphs arey=(1/3)x^2
and y=3
they intersect at x=3
so the limits are x=0 and 3
to rotate it about y=k, minus k from every function

which evaluates to 72/5pi
A is asnwer
