For a class project, a teacher cuts out 15 congruent circles from a single sheet of paper that measures 6 inches by 10 inches. How much paper is wasted?

60 – 15π square inches

Step-by-step explanation:

Assuming a diameter of 2 inches for each circle, then because the height of the sheet is 6 inches and the length is 10 inches, 5 columns of 3 circles each, are formed (see picture attached).

The area of each circle is: (π*D^2)/4 = (π*2^2)/4 = π square inches

The area of the 15 circles is: 15π square inches

The area of the sheet is = 6*10 = 60 square inches

The wasted paper is equal to the difference between the area of the sheet and the area of all circles, that is, 60 – 15π square inches

x + 107

step-by-step explanation:

let's say that the number he had before the mistake was x. then, he will have 107 dollars more than this, so the answer is x + 107.

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35
