Using your algebra skills, how can you rearrange the formula for the volume of a cylinder, V = πr2h, to find an expression for h

sp2606 [1]

So you start with
V = πr^2h
you divide both sides by πr^2
(v/πr^2) = h

Write a division equation that has a solution of 12. Prove that your equation has a solution of 12 using algebraic methods.

IRINA_888 [86]

Answer:

The required equation is $\frac{y}{6} =2$ .

Step-by-step explanation:

Consider the provided information.

Write a division equation that has a solution of 12.

The required division equation is shown below:

$\frac{y}{6} =2$

Solve the above equation a shown.

$\frac{y}{6}\times 6=2\times 6$

$y=12$

Now check this with algebraic method.

The required tape diagram is shown below:

$\frac{12}{6} =2$

$2=2$

Which is true, Hence 12 is the correct answer.
