Answer:

There are 40 books total

Step-by-step explanation:

you need to set a proportion

The first fraction is 55/100 it's over 100 because it's percent

the other fraction is 22/x the 22 is out of a total number so that's why it's on top and x because you don't know the total number of books

then you multiply diagonally

55×x= 22×100

55x=2,200

Then you solve it like a regular equation by dividing both sides by 55

x=40

Can someone help me find the volume please

umka2103 [35]

Answer:

See below.

Step-by-step explanation:

The figure is a cone. The formula for the volume of a cone is:

$V=\frac{1}{3}\pi r^2h$

The radius is 4.8 and the height is 2.9. Substitute:

$V=\frac{1}{3}\pi (4.8)^2(2.9)$

Use a calculator:

$V\approx69.97\text{ km}^3$

And we're done!
