A) \[2640\text{ }cu\text{ }cm\]
B) \[2604\text{ }cu\text{ }cm\]
C) \[2460\text{ }cu\text{ }cm\]
D) None of these
Correct Answer: A
Solution :
\[\therefore \] Volume of pipe, \[V=\pi \left( r_{1}^{2}-r_{2}^{2} \right)\times h\] \[=\frac{22}{7}[{{(3.5)}^{2}}-{{(2.5)}^{2}}]\times 140\] \[=\frac{22}{7}(12.25-6.25)\times 140\] \[=22\times 6\times 20=2640\,cu\,cm\]You need to login to perform this action.
