We are given 3 equations. Using these equations we can find f(h(2)).
h(x)=7x-5
h(2)=7(2)-5
h(2)=14-5
h(2)=9
f(x)=x^2-7
f(h(2))=(7x-5)^2-7
we know the answer for h(2) by now, so we can substitute for that.
f(9)=9^2-7
f(9)=81-7
f(9)=74
so f(h(2))=74

Volume of a cylinder = πr²h
where,
r is the radius of the cylinder
h is the height of the cylinder
Area of the rectangle = length X breadth
We can consider that a rectangle if rotated will form a cylinder.
In that case, the breath of the rectangle will become the diameter of the cylinder and the length will become the height of the cylinder.
