<span>The correct answer is that y does not vary directly with x.
Explanation<span>:
If y varies directly with x, this means that it would fit the equation y=kx for every point in the set.
For the first point, we would have 11=7k; this would mean that k=11//7.
For the second point, we would have 13=8k; this would mean that k=13/8.
Checking using proportions shows us that 11/7 does not equal 13/8:
cross multiply, and you have 11*8=7*13, or 88=91.
This is not true, so k is not a constant, and y does not vary directly with x.</span></span>
S= (pi times r times l) + (pi times radius squared)
Factor out the pi times r
S= (pi times r) l + r
Divide
S/(pi times r)= l + r
Find common denominator and subtract
(S- pi times r)/(pi times r) = l
The answer therefore is A
