<h3>What is Volume of cylinder?</h3>

The volume of a cylinder is the number of unit cubes (cubes of unit length) that can be fit into it. It is the space occupied by the cylinder as the volume of any three-dimensional shape is the space occupied by it.

The water tank is in the shape of cylinder whose radius = 5 feet

and, height= 11 feet

Volume of water tank =\pi r^{2} h

                                    = 3.14 * 5 * 5 * 11

                                    = 3.14*25*11

                                   = 863.50 ft^{3}

Hence the water tank hold 863.50 ft^{3} of water.

Can someone please tell me if i am right?
pentagon [3]
Second one is correct, that is an identity.

Third one is a contradiction:
6x - 15 = 3 * (2x - 6)    ------>    6x - 15 = 6x - 18

Fourth one:
5x - 3 * (x - 4) = 2 * (x - 6) ---> 5x - 3x + 12 = 2x - 12 ---> 2x + 12 = 2x -12
So this is a contradiction as well.
