A cylindrical piece of iron pipe is shown below. The wall of the pipe is 1.25 inch thick:

The figure shows a cylinder of height 16 inches and diameter 6 inches.

What is the approximate inside volume of the pipe?

88 cubic inches
49 cubic inches
142 cubic inches
154 cubic inches

inside volume of the pipe is 154 cubic inches

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

h represents the height of the cylinder.

r represents the radius of the cylinder.

π is a constant whose value is 3.14

From the information given,,

Diameter of outer cylinder = 6 inches

Thickness of pipe = 1.25 inches

Diameter of inner cylinder = 6 - (2 × 1.25) = 6 - 2.5 = 3.5 inches

Radius = diameter/2 = 3.5/2

Radius = 1.75 inches

Height = 16 inches

Therefore

Inside volume of pipe = 3.14 × 1.75² × 16 = 154 cubic inches to the nearest whole number.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
