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.

7πy2 - 2x2

What does the term 7πy2 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

Answer 1

wellllllll
the equation for the area of a circle is
\[A= \pi r^2\]

Answer 2

if the radius of the circle is y
r= y

and there are a total of 7 circles

then

Answer 3

So, what do you think the answer is?

Answer 4

@completeidiot A, the total area of seven circles?

Answer 5

yes good job
