Answer 1

Answer:

Question:

Find the Volume of a Cylindrical Tank whose radius is 10cm and the height is 21cm. (Take π = ${\bold{\frac{22}{7}}}$)

Answer:

We know that,

$\quad$$\quad$${ \boxed{ \sf{Volume \: of \: Cylinder =\pi {r}^{2}h }}}$

➛ ${ \large{\frac{22}{7} \times {(10)}^{2} \times 21}}$

➛ ${ \large{ \frac{22}{7} \times 10 \times 10 \times 21 }}$

➛ ${ \large{ \frac{22}{7} \times 100 \times 21 }}$

➛ ${ \large{ \frac{22}{{ \cancel{7}} ^{1} } \times 100 \times { \cancel{21}}^{3} }}$

➛ $22 \times 100 \times 3$

➛ $22 \times 300$

➛ ${ \boxed{ \green{6600{ \rm{ {cm}^{3}}} }}}$

Thus, The volume of Cylindrical Tank is${ \bold{ \: 6600{ { \bold{ {cm}^{3}}} }}}$.
