Question

~NEEDED ASAP, PLEASE HELP<3~
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.

7πy2 - 2x2
What does the term 7πy2 in the expression represent?

Answer 1

\(y\) is defined in the problem statement. It is the radius of each circle.
\(\pi y^{2}\) is then the area of just one of the circles.
\(7\pi y^{2}\) is the area of all 7 circles.
