Answer:

W = 21.44*10⁶J

Step-by-step explanation:

Given

y = x² (0 < x < 4)

γ = 10000 N/m³

W = ?

If we apply

y = 4² = 16 = h

y = x² ⇒ x = √y

then

V = π*(√y)²*dy = π*y*dy

W = (γ*V) *(16-y) = γ*π*y*dy*(16-y)

⇒ W = γ*π*∫y*(16-y)dy = γ*π*(8y²-(y³/3))

finally we obtain (0 < y < 16)

W = γ*π*(8y²-(y³/3)) = 10000*π*(8*16²-(16³/3)) = 21.44*10⁶J
