Question

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

Answer 1

Answer:

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
