Question

a cylindrical jar is filled 80% with juice jar with height 40 cm and diameter 7 cm find volume of juice in lit ​

Answer 1

Answer:

1232cm^3

Step-by-step explanation:

Volume of cylinder =

$v = \pi {r}^{2} h \\ = \pi { \frac{d}{2} }^{2} h \\ = \frac{\pi}{4}{d}^{2} h$

d=7cm and h=40cm therefore,

$v = \frac{\pi}{4} \times 7 \times 7 \times 40 \\ = \frac{22 \times 7 \times 7 \times 40}{7 \times 4} \\ = 22 \times 7 \times 10 \\ = 1540 {cm}^{3}$

80% of Volume =

$= \frac{80}{100} \times 1540 \\ = 154 \times 8 \\ = 1232 {cm}^{3}$
