Question

Rearrange the formula A = πab 4 for b.

Answer 1

Answer:

The required formula is  $b=\frac{4A}{\pi a}$ .

Step-by-step explanation:

The given formula is

$A=\frac{\pi ab}{4}$

Multiply both sides by 4.

$A\times 4=\frac{\pi ab}{4}\times 4$

$4A=\pi ab$

Divide both sides by πa.

$\frac{4A}{\pi a}=\frac{\pi ab}{\pi a}$

$\frac{4A}{\pi a}=b$

Therefore required formula is  $b=\frac{4A}{\pi a}$ .

Answer 2

So i think the formula is A=πab. To isolate b you divide by πa on both sides so you end up with:

A/(πa)=b
