Adesigner wants to make a circular fountain inside a square of grass as shown at the right. what is a rule for the area a of the grass as a function of r?

see the attached figure to better understand the problem

we know that

the area of a square is equal to

where

b is the length side of the square

in this problem, the length side of the square is equal to the diameter of the circle

so

b=2r

substitute in the formula of the area of the square

Find the area of the circle

the area of the circle is equal to

Find the area of the grass

the area of the grass is the area of the square minus the area of the circle

so

therefore

the answer is

the area A of the grass as a function of r is equal to

you forgot the options, but i found them anyways, the correct answer is "john wilson believes that words and actions based on the intellect are superior to those based on emotions".

john wilson is depicted as an extremely intelligent man. the point of the excerpt is to make a sort of distinction between emotional and rational intelligence. he happens to have both attributes, but he clearly favors his intellectual gifts. at the same time, because of his religious background, he's a little bit conflicted with this and it makes him ashamed.

hope this !
