Answer 2

❏ Question:-

An oil can is in the form of cylinder whose radius is 7.7 cm and length is 56 cm. Find the quantity of oil in litres that can be stored in the can

❏ Solution:-

Cylinder:-

$\setlength{\unitlength}{1 cm}\begin{picture}(12,4)\thicklines\put(2.7,2.7){ . }\put(6,3){\circle{2}}\put(6,6){\circle{2}}\put(6,3){\line(0,1){3}}\put(5.3,3){\line(0,1){3}}\put(6.7,3){\line(0,1){3}}\put(6,3){\line(1,0){0.7}}\put(6,6){\line(1,0){0.7}}\put(6.2,6.13){ r }\put(6.8,4.5){ h }\end{picture}$

✦given:-

• radius (r)=7.7 cm

•height or length (h)=56 cm.

Hence, Volume of the cylinder is ,

$\sf\implies Volume=\pi r^2 h$

$\sf\implies Volume=\frac{22}{\cancel7}\times 7.7^2 \times\cancel{56}$

$\sf\implies Volume=22\times7.7\times7.7\times8$

$\sf\implies Volume=10435.04 \:cm^3$

$\sf\implies \boxed{\large{\red{Volume=10.43504 \:litres}}}$

∴ Quantity of oil that can be stored is

=10.43504 L.
