Question

mister Chandra installed a cylindrical water tank on the roof of his house .find the capacity of the tank in litre if its radius is 2.8 metre and height 3.5 metre.​

Answer 1

$\underline { \blue { Dimensions \:of \:a \: cylidercal \:tank : }}$

$Radius (r) = 2.8 \:m , \: Height (h) = 3.5 \:m$

$\boxed { \pink { Volume \: of \:a \: cylinder = \pi r^{2}h }}$

$Capacity \: of \: the \:tank \\= Volume \:of \:the \: cylinder \\= \pi r^{2} h \\= \frac{22}{7} \times (2.8\:m)^{2} \times 3.5 \:m \\= 22 \times 0.4 \times 2.8 \times 3.5 \:m^{3} \\= 86.24 \: m^{3} \\= 86.24 \times 1000 \: litres \\= 86240 \: litres$

Therefore.,

$\red { Capacity \: of \: the \:tank} \green {=86240 \: litres}$
