Solve the indicated variable:
1. Volume of a cone: solve for h: V=¨ir^2h/3
2. Temperature formula: solve for C: F=9/5C+32
pleaseeeee help me solve these! plzzz! i have nooo idea how to do these. THANKS! =)))

your first formula should have been
V = pi(r^2)(h/3)
multiply by 3
3V = pi(r^2)h
divide by pi(r^2)
3V/(pi(r^2)) = h
in the second , multiply each term by 5
5F = 9C + 160
9C = 5F  160
9C = 5(F  32)
C = (5/9)(F32)
