Four congruent circular holes with a diameter of 2 in. were punches out of a piece of paper.

What is the area of the paper that is left? Use 3.14 for pi

For this case we first calculate the area of the complete rectangle.

We have then:

A1 = (8.5) * (11)

A1 = 93.5

Then, we calculate the area of each circle:

A2 = pi * r ^ 2

A2 = (3.14) * (2/2) ^ 2

A2 = 3.14

The total area is given by:

A = A1 - 4 * A2

A = 93.5 - 4 * (3.14)

A = 80.94 in ^ 2

Answer:

A) 80.94

Answer:80.94
