Answer:

The best estimate is 64% I think

Step-by-step explanation:

I got this by subtracting 64 from 75 to get 11 which would be turned into a percent, and 75 minus 11% is 66.75, which is the closest estimate. Sorry if I am wrong, but still hope I helped.

Pi x 36 - 16 Need help on this please answer appropriate.

Bad White [126]

Answer:

To do this question, we must first convert Pi to a decimal form, as shown below:

Pi = 3.14

So then our equation becomes:

3.14 x 36 - 16

We still need to remember PEMDAS.

Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.

So according to PEMDAS, we need to do 3.14 x 36, which equals 113.04

Now we have to do:

113.04 - 16 = 97.04

Our answer is 97.04

Hope this helps - genius423

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

Maslowich

Answer:

16 pi cubic units

Step-by-step explanation:

Given that a region is bounded by

$f(x)=√x, y=0, x=1, x=4$

And the region is rotated about x axis.

We can find that here radius would be y value and height would be dx

So volume would be as follows:

If f(x) is rotated about x axis volume

= $\pi \int\limits^b_a {y^2} \, dx \\=\pi \int\limits^4_1 {x} \, dx\\=\pi *x^2 ^4_1\\= \pi*16-1\\=15\pi$

cubic units.
