The mass of the cylinder is 50,000 g. Find the density of the cylinder to the nearest tenth

answer choices

0.7 g/mm3

81.2 g/mm3

2.7 g/mm3

0.4 g/mm3

Density of the Cylinder = 2.7 g/mm³

Step-by-step explanation:

Density of a cylinder is calculated using the formula =

Mass of the Cylinder ÷ Volume of the Cylinder

Step 1

The First step is to find the Volume of the Cylinder.

Volume of a Cylinder = πr²h

In the attached image , we are given:

Diameter of the Cylinder = 28mm

Radius of the Cylinder = Diameter ÷ 2 = 28mm ÷ 2

Radius of the Cylinder (r) = 14mm

Height of the Cylinder (h) = 30mm

The Volume of the Cylinder = πr²h

= π × (14mm)² × 30mm

= 18472.564803 mm³

Step 2

The second step would be to find the Density of the Cylinder.

Density of the Cylinder = Mass of the Cylinder ÷ Volume of the Cylinder

Mass of the Cylinder = 50,000g

Volume of the Cylinder = 18472.564803 mm³

Density of the Cylinder = 50,000g ÷ 18472.564803 mm³

= 2.7067167193 g /mm³

Approximately the Density of the Cylinder = 2.7 g/mm³

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
