The external diameter of a pipe is 2 and half cmand the internal diameter is 2cm. What is the thickness of the metal in the pipe.
So the
external radius is 1.25 cm
and the internal radius is 1.0 cm
The difference is the thickness of the metal, right?
To find the thickness of the metal in the pipe, we need to subtract the internal diameter from the external diameter.
The external diameter is given as 2 and a half cm, which can also be written as 2.5 cm.
The internal diameter is given as 2 cm.
Subtracting the internal diameter from the external diameter:
2.5 cm - 2 cm = 0.5 cm
Therefore, the thickness of the metal in the pipe is 0.5 cm.
To calculate the thickness of the metal in the pipe, you need to subtract the internal diameter from the external diameter.
Given:
External Diameter = 2.5 cm
Internal Diameter = 2 cm
To find the thickness:
Thickness = External Diameter - Internal Diameter
Thickness = 2.5 cm - 2 cm
Thickness = 0.5 cm
Therefore, the thickness of the metal in the pipe is 0.5 cm.
