Using disks or washers, find the volume of the solid obtained by rotating the region bounded by the curves y=x−1 y=0 x=2 and x=5
Irina-Kira [14]
Using disks ...
V= \pi \int\limits^5_2 {(x-1)^{2}} \, dx =\pi(\frac{1}{3}(5^{3}-2^{3})-(5^{2}-2^{2})+(5-2))=21\pi

The volume is 21π units³ ≈ 65.97 units³

Need a bit of help with this question:
DiKsa [7]

Firstly let's find hypotenuse(let it will be "n" of smaller triangle

Let use Pythagorean theorem

a^{2}  +  {b}^{2}  =  {n}^{2}  \\  {20}^{2}  +  {10}^{2}  =  {n}^{2}  \\  n =  \sqrt{500}

Now we need to find hypotenuse(x) of bigger triangle

{c}^{2}  +  {n}^{2}  =  {x}^{2}  \\  {9}^{2}  +  { \sqrt{500} }^{2}  =  {x}^{2}  \\ x =  \sqrt{581}

The value of x must be rounded to 1 DP, so

\sqrt{581}  = 24.1039... \\  \sqrt{581}  \simeq \: 24.1

Answer: x=24.1

Step-by-step explanation:

2x^2 -9 = 121

        +9    +9

2x^2 = 130

/2         /2

x^2   = 65

x= sqrt (65)

x= 8.06225...
