The region bounded by y=5/x, y=0, x=1, and x=3 is rotated about the x-axis. find the volume of the resulting solid.

brilliants [131]

Volume of Revolution = $\pi \int\limits^b_a {y^{2}} \, dx$
Volume of Revolution = $\pi \int\limits^3_1 { (\frac{5}{x})^{2}} \, dx$
= $\pi \int\limits^3_1 ({\frac{25}{x^{2}}) \, dx$
= $25\pi \int\limits^3_1 ({\frac{1}{x^{2}}) \, dx$
= $25\pi \int\limits^3_1 ({x^{-2}}) \, dx$
= $25\pi \ ^{3} [-x^{-1}] _{1} 
$
$= 25\pi\ ((-1/3) - (-1/1)) \\
= 25\pi\ (2/3) \\
= 50/3 \pi\ units^{3}$

The ratio of adult to children is 5:2, There are 35 adults at the museum, how many children are there

Black_prince [1.1K]

Answer:

14 children

Step-by-step explanation:

If we know the ration, and we are given the adults, we can set up a proportion in order to solve for the amount of children there are.

5:2=35:x

5x=35*2

5x=70

x=14

There are 14 children
