Given:
m = 12 g, the mass of the cylinder
r = 2 cm, the cylinder's radius
h = 6 cm, the height of the cylinder.

To find the volume, V, of the cylinder:
V =  πr²h
=  π*(2 cm)²*(6 cm)
= 75.398 cm³

Density is defined as:
density = mass/volume.

Thus,
density = m/V
= (12 g)/(75.398 cm³)
= 0.159 g/cm³
= 0.16 g/cm³ (rounded to the nearest hundredth)

Answer: 0.16 g/cm³

lana [2441]
Work is defined as being completed when an object shifts as a result of an applied force. It is calculated by multiplying the force exerted by the distance moved as a result of that force. It can be represented as: W = Force x distance W = 84 J = F (7.0 m) F = 12 N I hope this provides clarity.

How do genetic modification variations likely differ from genetic sexual reproduction?
vlada-n [2515]

The variations caused by genetic modification lead to alterations in the organism's genome. Such changes express traits in ways that differ from the typical. These variations can cause genetic mutations that may be passed down generations.

In the case of sexual reproduction, the organism's genome remains unchanged. Here, only an exchange occurs between the alleles inherited from each parent, and this does not result in mutations.
