Question

Please solve this question for a

Answer 1

a = (8A)/(\pi r^(2))+1

Explanation:

Answer 2

`a = \frac{8A}{\pi {r}^(2) } + 1 \\`

Explanation:

`A = (1)/(8) \pi {r}^(2) (a - 1) \\`

First of all multiply through by 8 to eliminate the fraction

That's

`8A = 8 * (1)/(8) \pi {r}^(2) (a - 1) \\8 A = \pi {r}^(2) (a - 1)`

Divide both sides by πr²

`\frac{8A}{\pi {r}^(2) } = \frac{\pi {r}^(2)(a - 1) }{\pi {r}^(2) } \\ a - 1 = \frac{8A}{\pi {r}^(2) }`

Move 1 to the other side of the equation to make a stand alone

We have the final answer as

`a = \frac{8A}{\pi {r}^(2) } + 1 \\`

Hope this helps you
