Idon't exactly understand how to do this could someone explain it v = 1/3 πr2h for h.

What it is asking you to do is solve for h rather than V. You want h all by itself on one side of the equation.

Step One

Multiply both sides by 3

3*V = 3*(1/3 r²h

3V = r²* h Divide both sides by r²

. . . . . . Divide by pi

<<<<<< Answer

-14 is the answer

hope this : ))
