Verified Answer
The volume of a metallic cylindrical pipe is 748cm2 its length is 14 c...
The volume of the metallic cylindrical pipe = 748 Cm^3
length of the cylindrical pipe h =14 cm
the external radius of the pipe R = 9 cm
let the internal radius of the cylindrical pipe be r cm.
therefore the volume of the metallic pipe= π(R1^2-r2^2)h
therefore
The thickness of the metallic pipe = R - r = 9-8 = 1 cm

Given:
Volume of the cylindrical pipe = 748 cm³
Length of the pipe (height) = 14 cm
External radius of the pipe = 9 cm
To find: Thickness of the pipe.
Solution:
We can find the thickness of the pipe by subtracting the internal radius from the external radius. Let's assume the internal radius of the pipe is 'r'.
Step 1: Calculating the internal radius:
The volume of a cylinder can be calculated using the formula:
Volume = π * r² * h
Given that the volume of the pipe is 748 cm³ and the height is 14 cm, we can rearrange the formula to solve for the internal radius:
748 = π * r² * 14
748 = 14πr²
r² = 748 / (14π)
r² ≈ 16.9
r ≈ √16.9
r ≈ 4.11 cm
Step 2: Calculating the thickness:
The thickness of the pipe is the difference between the external radius and the internal radius.
Thickness = External radius - Internal radius
Thickness = 9 cm - 4.11 cm
Thickness ≈ 4.89 cm
Therefore, the approximate thickness of the metallic cylindrical pipe is 4.89 cm.
Summary:
The thickness of the metallic cylindrical pipe is approximately 4.89 cm.
Volume of the cylindrical pipe = 748 cm³
Length of the pipe (height) = 14 cm
External radius of the pipe = 9 cm
To find: Thickness of the pipe.
Solution:
We can find the thickness of the pipe by subtracting the internal radius from the external radius. Let's assume the internal radius of the pipe is 'r'.
Step 1: Calculating the internal radius:
The volume of a cylinder can be calculated using the formula:
Volume = π * r² * h
Given that the volume of the pipe is 748 cm³ and the height is 14 cm, we can rearrange the formula to solve for the internal radius:
748 = π * r² * 14
748 = 14πr²
r² = 748 / (14π)
r² ≈ 16.9
r ≈ √16.9
r ≈ 4.11 cm
Step 2: Calculating the thickness:
The thickness of the pipe is the difference between the external radius and the internal radius.
Thickness = External radius - Internal radius
Thickness = 9 cm - 4.11 cm
Thickness ≈ 4.89 cm
Therefore, the approximate thickness of the metallic cylindrical pipe is 4.89 cm.
Summary:
The thickness of the metallic cylindrical pipe is approximately 4.89 cm.
