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

 A) 80.94

Step-by-step explanation:

80.94

Step-by-step explanation

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
