Chapter 6: Q. 44 (page 511)

Consider the region between the graph of and the line $y = 5$ on $[0, 2]$ . For each line of rotation given in Exercises 41–44, use definite integrals to find the volume of the resulting solid.

Short Answer

Expert verified

The volume of the solid is $\frac{206}{15} π$

Step by step solution

Step 1. Given Information

The given figure is

$f (x) = 4 - x^{2} = y x = \sqrt{4 - y} = g (y)$

Step 2. Finding Volume

$V = π \int_{a}^{b} {(R (x))}^{2} dx = \int_{0}^{2} {(5 - (4 - x^{2}))}^{2} dx V = \int_{0}^{2} (x^{4} + 2 x^{2} + 1) dx$

$V = π {(\frac{x^{5}}{5} + \frac{2 x^{3}}{3} + x)}^{2}_{0} V = π (\frac{32}{5} + \frac{16}{3} + 2 - 0) V = \frac{96 + 80 + 30}{15} = \frac{206}{15} π$
