nasty-shy [4]

Answer:

8/17

Step-by-step explanation:

The sine of an angle is defined as the opposite side to the reference angle divided by the hypotenuse.

The side opposite the angle is always the side not connected to the reference angle. In this case the opposite side = ZY

The hypotenuse = XZ

Sin(X) = ZY/XZ

Sin(X) = 1634 = 8 / 17

What is the volume of the cylinder below?

Anestetic [448]

Answer:

Step-by-step explanation:

The formula for volume of cylinder is given below:

volume of cylinder = $\pi r^2 h$

Where r is the radius (here, it is given as 3)

h is the height, the perpendicular distance from base to top (here, it is 4 NOT 5 since 5 is the 'slant height')

Plugging in the available info , we get our answer:

$\pi r^2 h\\=\pi (3)^2 (4)\\=36\pi$

B is the correct answer
