Question

A milk tank in form of cylinder radius 1.4m and height 8 cm. Find quantity of milk in litre that can stored in tank
.

Answer 1

${\bold{\underline{\underline{Answer:}}}}$

${\bold{\therefore Volume\:of\:tank=0.4928\:m^{3}}}$

${\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\underline \bold{Given : } \\ \implies Height(h) = 8 \: cm \\ \\ \implies Radius (r)= 1.4 \: m \\ \\ \underline \bold{To\: Find: } \\ \implies Volume \: of \: tank = ?$

• According to given question :

$\bold{Height = 8 \times \frac{1}{100} = 0.08 \: m} \\ \\ \bold{Using \: formula \: of \: Volume \: of \: cylinder : } \\ \implies Volume \: of \: cylinder = \pi {r}^{2} h \\ \\ \implies Volume = \frac{22}{7} \times (1.4 )^{2} \times 0.08 \\ \\ \implies Volume = 22 \times 1.4 \times 0.2 \times 0.08 \\ \\ \bold{\implies Volume = 0.4928 \: m^{3} } \\ \\ \bold{\therefore Volume \: of \: tank= 0.4928 \: {m}^{3} }$

Answer 2

Answer:

492800

Step-by-step explanation:

volume of a cylinder = 22/7×r × r×h

= 22/7×140×140×8

= 22×20×140×8

= 440×1120

=492800 cm sq./4928m.sq.

Note:since radius is in metre and height is in cm we have converted

radius 1.4into 140 (1.4 ×100)
