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

In ABC, centroid D is on median AM. AD = x + 5 and DM = 3x – 5. Find AM
Sindrei [870]

Answer

Find out the value of AM.

To prove

As given

In ABC,

centroid D is on median AM.

AD = x + 5 and DM = 3x – 5.

By using the centroid property

The centroid divides each median in a ratio of 2:1.

Thus D divide the median AM  in a ratio of 2:1.

Therefore

(AD) = 2DM

(x + 5) = 6x – 10

5x = 15

x = \frac{15}{5}

x = 3

Now

AM = 3+ 5

     = 8 unit

DM = 3 × 3- 5

      = 4 unit

AM = AD + DM

      = 8 + 4

AM   = 12 unit

Therefore the AM is 12 unit.
