Question

a metalic pipe whose internal and external diameters are 8m and 6m,has length of 2.1m.Find the volume of the metal​

Answer 1

Answer:

184.73 $m^{3}$

Step-by-step explanation:

Formula Used: V= $\pi$ $r^{2}$ h

Volume of pipe using the external diameter = 422.23 $m^{3}$

Volume of pipe using the internal diameter = 237.5 $m^{3}$

Volume of metal = Volume of pipe using external diameter - volume of pipe using internal diameter

422.23 - 237.5 = 184.73 $m^{3}$
