Given the formula V=2pie squareroot(2gh)
hope you can understand that.
(i)Rearrange to make h the subject of the equation
V=2pie squareroot(2gh)
V/(2pi)=sqrt(2gh)
2gh=(V/(2pi))^2
h=[(V/(2pi))]^2/[2g]
h=[(V/(2pi)]^2/[2g]
-------------------
(ii) Find h when V=70 and g =9.81
h=[70/2pi]^2/[2*9.81]
h=[11.14^2]/19.81]
h=[124.0996]/[19.81]
h=6.26449...
