Help.... and thanks
Archy [21]

Answer:

π

Step-by-step explanation:

The *period* of a function is the length it takes before it repeats. Usually, the period of the sine function is 2π; it takes a full rotation around the unit circle for it to repeat. When we replace the input x with -2x, this does a few things:

- Changes the rotation direction

- Makes the rotation go twice as fast

If we rotate around the unit circle twice as fast, it’ll take us half of 2π, or just π to complete a cycle.

What is the mass of a cylinder of lead with a radius of 2 centimeters and a height of 6 centimeters, given that the density of l
ycow [4]

The mass of lead cylinder is: 859.10 grams

Step-by-step explanation:

In order to find the mass of a cylinder we have to find the volume first

Given

Radius = r = 2 cm

Height = h = 6 cm

The volume of cylinder is given by:

V = \pi r^2h

Putting the values

V = 3.14 * (2)^2 * 6\\= 3.14*4*6\\=75.36\ cm^3

Now,

Density of lead per cm^3 = 11.4g

Mass\ of\ cylinder = Volume*Density\\= 75.36*11.4\\=859.10\ grams

The mass of lead cylinder is: 859.10 grams

Keywords: Volume, Density
