Question

find the height of the cylinder whose volume is 2.54 cubic meters and diameter of the base is 140cm

Answer 1

${\purple{\huge{hello!}}}$

Diameter=140cm
Radius=140/2
=70 cm
in meters:-
1cm=1/100m
70cm=0.7m(r)
Volume=2.54m³

height=?

Volume of cylinder=πr²h
2.54=22/7×0.7×0.7×h
2.54=22×0.1×0.7×h
2.54=22×0.07×h
2.54=1.54h
h=2.54/1.54
h=1.649
h=1.65 meters (approx)
${\boxed{\orange{\huge{h{={165{cm}}}}}}}$
