Algorithm estimating a volume of revolution

Consider the following algorithm used to estimate a volume of revolution.

define f(x)
    return √(x + 1)
sum ← 0
a ← 1
b ← 3
left ← a
while left ≤ b
    volume ← π(f(left))²
    sum ← sum + volume
    left ← left + 1
end while
print sum

The algorithm above will print the value
