Question

PLEASE HELL ME!!!!

Find the density of a cylinder on Earth that weighs 14 kg, a height of 25 cm, and a diameter of 4 cm.​

Answer 1

The answer is 0.045 kg/cm³

Step-by-step explanation:

The density of a substance can be found by using the formula

From the question

mass of cylinder = 14 kg

Volume of a cylinder = πr²h

where

r is the radius

h is the height

From the question

h = 25 cm

The volume of the cylinder is

We have

volume = 314.159 cm³

The density of the cylinder is

We have the final answer as

0.045 kg/cm³

Answer 2

The answer is 0.045 kg/cm³

Step-by-step explanation:

The density of a substance can be found by using the formula

`density = (mass)/(volume) \\`

From the question

mass of cylinder = 14 kg

Volume of a cylinder = πr²h

where

r is the radius

h is the height

`radius = (diameter)/(2) \\`

From the question

h = 25 cm

`r = (4)/(2) = 2 \: \: \: cm`

The volume of the cylinder is

`V = {2}^(2) (25)\pi \\ = 4 * 25\pi \\ = 100\pi \\ = 314.159265...`

We have

volume = 314.159 cm³

The density of the cylinder is

`density = (14)/(314.159) \\ = 0.044563421...`

We have the final answer as

0.045 kg/cm³
