Hi,

To find the volume of cylinder this formula is required.

$v = \pi {r}^{2} h$

To get radius you need to divide diameter with 2 like this.

$80 \div 2 = 40$

Now just put your values into formula.

$v = \pi {40}^{2} \times 130 \\ v =653451.27$

You will need 653451.27 cubic centimetres of concrete.

Hope this helps.

It would actually be -14 because 5+4-2=7 and if you multiply 7 by -2 you get -14

Suppose triangle ABC has vertices at A(1, 0), B(10, 0), and C(2, 6). After a 60° counterclockwise rotation about the origin, ver

Artemon [7]

Check the picture attached.

Let OB be the radius of circle with center O.

Let B' be the image of B after the described rotation

OB and OB' are sides of the equilateral triangle OBB'.

The x coordinate of B' is the midpoint of OB, that is 5.

In the right triangle B', point (5, 0) and B:

Distance point (5, 0) to B is 5
|B'B|=|OB|=10

so by the pythagorean theorem:

$a= \sqrt{ 10^{2} - 5^{2} } = \sqrt{ 2^{2} *5^{2} - 5^{2} }= \sqrt{5^{2}(4-1)}=5 \sqrt{3}$ units

Answer: $5 \sqrt{3}$
