Answer:
9 times. 54 divided by 6 is 9.
Step-by-step explanation:
I think it would be b or c
Each cross section has a diameter equal the horizontal distance between the two "halves" of the parabola. We have
y = 4x² ⇒ x = ±√y/2
so the diameter for some given y would be √y/2 - (-√y/2) = √y.
The volume of a cross section with thickness ∆y is then
π/2 (√y/2)² ∆y = π/8 y ∆y
The total volume of the solid would then be
2/7x+6=10. Subtract 6 from both sides
-6. -6
(7/2) 2/7x= 4 (7/2) Multiply both sides by the reciprocal of 2/7
X= 14. The fractions cancels out and x=14
