What is the perimeter of rhombus WXYZ? units 12 units units 20 units

timama [110]

Let O be the intersection of the vertical line through ZX, and the horizontal line through YW.

The coordinates of this point are clearly (5, 2) as it is at the same x-coordinate as X and Z, and y-coordinate as Y and W.

So, YZO is a right triangle. By the Pythagorean theorem:

$ZY= \sqrt{{YO}^2+{OZ}^2}= \sqrt{2^2+3^2}= \sqrt{4+9}= \sqrt{13}$ .

Since all sides of a rhombus are equal, then the perimeter is :

$P(XWZY)=4 \sqrt{13}$ units.

Answer: third choice.

PLEASE HELP! Find the height of a cylinder with a surface area of 108 pi square meters. The radius of the cylinder is twice the

Naily [24]

Assuming the cylinder is closed at both ends
Surface area = 2 pi r^2 + 2 pi r h = 108

now h = r/2 so we have:-

2pi r^2 + pi r^2= 108

3 pi r^2 = 108
r^2 = 11.459
r = 3.385
so the height h = 1.693 m to nearest thousandth
