Question

Erica has 8 squares of felt, each with area 16. For a certain craft project she cuts the largest circle possible from each square felt. What is the combined area of the excess felt left over after cutting out all the circles?

A) 4(4-pi)
B) 8(4-pi)
C) 8(pi-2)
D) 32(4-pi)
E) 16(16-pi)

Answer 1

So each square has an area of 16 units^2, so each side is 4 units.
the circle on each square will have a radius of 2 units, for an area of π(2^2) or 4π

so the left over from each square is 16 - 4π units
or 4(4 - π)

Now, how many squares did you have ?

Answer 2

Okay.. I worked on The problem a little more, but I got D.

Because the area of the squares would be 32(4)
The area of the circles is 32pi

So then wouldn’t the answer be 32(4-pi)
