The minimum thickness of the book would simply be the sum of the thickness of the two cover pages and all the pages in between. That is:

minimum thickness = 0.9 mm * 2 + 0.13 mm * 400

minimum thickness = 53.8 mm

Circle A is shown with a central angle marked 30 degrees and the radius marked 5 inches.

anyanavicka [17]

The area for a sector of a circle is $A=\frac{\theta}{360}*\pi r^2$ . If our angle is 30 and our radius is 5, that fits in like so: $A=\frac{30}{360}\pi (5)^2$ . It appears that the first choice is what we want except you forgot to square all the radii.

Share 3200 ml of water in the ratio 4:1:3

Amiraneli [1.4K]

Answer:

1600 ml, 400 ml, 1200 ml

Step-by-step explanation:

Given ratios are: 4:1:3

Let the shares of the given ratios be 4x, x, 3x

$\therefore \: 4x + x + 3x = 3200 \\ \\ \therefore \: 8x = 3200 \\ \\ \therefore \: x= \frac{ 3200}{8} \\ \\ \therefore \: x=400 \\ \\ \implies \\ 4x = 4 \times 400 = 1600 \\ \\ 3x = 3 \times 400 = 1200 \\ \\$
