Question

The radius of a well is 1.4 m and its depth
is 10 m. Find the quantity of soil that had
been taken out to dig the well.​

Answer 1

$\sf{radius \: of \: the \: well = 1.4 \: m}$

$\sf{depth \: of \: the \: well = 10 \: m}$

$\sf{the \: well \: is \: in \: the \: form \: of \: cylinder.}$

$\sf{volume \: of \: well\: = 2\pi rh}$

$= > 2 \times \frac{22}{7} \times 1.4 \times 10$

$= > \: \: \sf{88 \: {m}^{2} }$
