Answer:
271.3 mm^3
Step-by-step explanation:
Volume of a cylinder = πr^2h
To find the answer, we need to find the difference between the large cylindrical and small cylindrical pipes.
V = π h (R^2 – r^2)
Given: h= 10, R is outer radius = 8.4/2 = 4.2, r is inner radius = 6/2 = 3
V = π (10) (4.2^2 – 3^2)
V= 3.14*10(17.64 - 9)
V = 31.4(8.64)
V = 271.3 mm^3
The volume of metal in the pipe 271.3 mm^3
Hope this will helpful.
Thank you.
To solve this problem, we simply use the equation of volume for hollow cylinders:
where V is volume, h is height = 10, R is outer radius = 8.4/2 = 4.2, r is inner radius = 6/2 = 3
<span>V = 86.4π = 271.43 mm^3</span>
