* hi if u answer this question correctly I will mark your answer brain list or whatever it's called ​

Answer 1

Answer:

volume= πr²h

convert 3080000ltr into meter cube

3080000/1000= 3089

3080= πr²h

3080= 22/7× r²× 20

3089×7= 440× r²

21560= 440×r²

21560/440= r²

49=r²

√49= 7

r= 7 cm

diameter= 2r

D=2×7= 14m
