Answer 1

$\mathbb{\huge{\pink{ANSWER}}}$

_________________⭐️⭐️⭐️⭐️

GIVEN

r=70 cm

r=0.7 m

h=1.5

volume=22/7*r2*h

=22/7*0.49*1.5

=2.31 m3

THE ANSWER IS 2.31 METRE CUBE

Answer 2

r=70cm

h=150cm

1000cm³=1L

volume of cylinder=capacity of cylinder

=πr²h

=22/7*70*70*150

=2310000

therefore L of water

=2310000/1000=2310L
