Exercise 39 Page 113

Apply inverse operations to isolate h.

h=3V/π r^2

Practice makes perfect

To solve the given formula for h, we will use the Properties of Equality to apply inverse operations on the formula. Remember, only like terms can be combined.

V=1/3π r^2h

MultEqn

LHS * 3=RHS* 3

3V=π r^2h

DivEqn

.LHS /π r^2.=.RHS /π r^2.

3V/π r^2=π r^2h/π r^2

CancelCommonFac

Cancel out common factors

3V/π r^2=π r^2h/π r^2
