The largest possible circle is cut out of a square whose side length is 8 feet. what will be the approximate area, in square feet, of the remaining board? ( where )

The approximate area of the remaining board is

Step-by-step explanation:

we know that

The area of the remaining board is equal to the area of the square minus the area of the circle

so

where

---> side length of the square

--> radius of the largest possible circle

substitute the values

wheres graph

step-by-step explanation:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
