Plz find any question plz

Q11

Suppose the two numbers are x and y so xy = 3000

the HCF = 10

we know that product of two numbers = product of their HCF and LCM

XY = HCF * LCM

3000 = 10 * LCM

3000/10 = LCM

300 = LCM

Answer 300

Q12 : Let us say second number is x so

product of x and 160 = product of HCF and LCM of ( x and 160 )

160 x = 32 * 1760

x= 32 * 1760 / 160

x= 352

Answer : 352

Find the volume of the solid of revolution formed by rotating about the x--axis the region bounded by the given curves.

Answer:

$V = \frac{8\pi}{3}$

Step-by-step explanation:

For this case we are interested on the region shaded on the figure attached.

And we can find the volume with the method of rings.

The area on this case is given by:

$A(x) = \pi [f(x)]^2 = \pi r^2 = \pi [3x]^2 = 9\pi x^2$

And the volume is given by the following formula:

$V= \int_{a}^b A(x) dx$

For our case our limits are x=0 and x=2 so we have this:

$V = \pi \int_{0}^{2} x^2 dx$

And if we solve the integral we got this:

$V= \pi [\frac{x^3}{3}]\Big|_0^{2}$

And after evaluate we got this:

$V=\pi [(\frac{8}{3} )-(\frac{0}{3} )]$

$V = \frac{8\pi}{3}$
