Write following expressions in Python: πr²h

What would following code fragments result in? Given x = 3.
(a) 1 < x
(b) x >= 4
(c) x == 3
(d) x == 3.0
(e) "Hello" == "Hello"
(f) "Hello" > "hello"
(g) 4/2 == 2.0
(h) 4/2 == 2
(i) x < 7 and 4 > 5.

\dfrac{1}{3} \pi r^2 h

\dfrac{1}{3} b^2 h

\sqrt{(x2 - x1)^2 + (y2 - y1)^2}
