# Rotation In Maths I

**Calculus**Level 5

There is a Figure bounded by the graphs of

1) \(y^{2} = 4x \)

2) \(y=0\)

3) \(x=0\)

4) \(x=1\)

It is Rotated About the Line \(x=1\).

Then The Volume of the Resulting Solid Figure Can Be Expressed As

\(\dfrac{a\pi}{b} \).

Then Find \(\textbf {a + b}\).

This Problem Is A Part Of Rotation In Maths.
