Question

The thickness of a metallic pipe is 1 cm. Its inner diameter is 12 cm. What is the volume of metal
needed for a pipe of length 1 m? [Tt = 3.14).


answer should be 4082cu.cm​

Answer 1

Answer:

d=12

r=?

$r = \frac{d}{2} = \frac{12}{2} = 6$

l=1m =1×100=100cm

Step-by-step explanation:

$volume \: of \: metallic \: pipe = \pi {r}^{2} h \\ = 3.14 \times {6}^{2} \times 100\\ = 3.14 \times 36 \times 100 \\ = 3.14 \times 3600 \\ = 11304$
