As we know that volume of a circle =πr2h
We have the diameter=7m radius=3.5
And now 539m=22/7x3.5x2xh
You cAn now easily solve it pl mark me Brainly if you want peace !

Answer:
diameter-7m
7/2-3.5 which is radius ....
radius - 3.5 m
*
π =22/7
height=?
volume of the cylinder = πrsquare.height
539 = 22/7×3.5. ×3.5 ×h
= 77/2
h= 539×2/77
77×7=539
7×2=14
so the answer is 14 m
