Saira is using the formula for the area of a circle to determine the value of .
klio [65]

For this problem, we just have to use the values we're given to calculate the approximate value of pi.

The formula presented is

\pi=Ar^{-2}

When you have a negative exponent, we can use the following property

a^{-b}=\frac{1}{a^b}

Using this property, our problem turns out to be

\pi=\frac{A}{r^2}

Now, we just need to plug the given values on this equation

\pi=\frac{50.265}{4^2}=3.1415625\approx3.142

The approximated value for pi is 3.142.

Neporo4naja [7]

It is clearly mentioned in the question that each bottle of ibuprofen has 1000 pills.

Now, 1/4 bottle of ibuprofen is used to make the prescription.

So, if one bottle of ibuprofen has 1000 pills and 1/4 1/4 bottle of ibuprofen is used to make the prescription, then Jerome obviously used \frac{1000}{4}=250 pills of ibuprofen to make the prescription.

This can be further explained as follows:

1 bottle=1000 pills

\therefore \frac{1}{4} bottle=\frac{1000}{4}=250 pills.
