Question

Which one of the given cylinders has greater volume and by how much?

Answer 1

volume of cylinder $\left(a\right)=\pi r^{2}h$

$=\pi \times 7\times 7\times 14$

$=\frac{22}{7}\times 7\times 7\times 14$

$=22\times 98$

$=2156c{m}^3$

volume of cylinder $\left(b\right)=\pi r^{2}h$

$=\frac{22}{7}\times 14\times 14\times 7$

$=4312c{m}^3$

volume of cylinder (b) > volume of cylinder (a)

by , $\Rightarrow 4312-2156$

$\Rightarrow 2156c{m}^3$
