Question

How do I solve this?

Answer 1

Answer:

Step-by-step explanation:

The first thing you have to do, is rewrite the given expression

$Ar^{-2} = \frac{A}{r^{2} }$

Then you plug in the given values

$\frac{A}{r^{2} } = \frac{50.265}{4^{2} }$

Finally you simplify

$\frac{50.265}{4^{2} }=\frac{50.265}{16} = 3.142$
