Question

Sandy cut out 2 squares and 7 circles from a piece of cardboard. The length of the sides of each square was x inches, and radius of each circle was y inches. The expression below shows how many more square inches of cardboard Sandy used for making the circles than the squares:

7πy^2 - 2x^2

What does the term 7πy^2 in the expression represent?

The total area of 7 circles

The total area of 22 circles

The total area of all the shapes

The total area of all the squares

sRRY NOT GOOD WITH MATH LOL

Answer 3

ok;;;;;;0

Answer 4

the area of each square is x^2...and there are 2 of them (2x^2).
the area of each circle is (pi)y^2...and there are 7 of them (7(pi)y^2).

because the expression is finding how much more was used in the circles than the squares, they subtracted the total square area from the total circle area...
