Answer:
3.9 in^2
Step-by-step explanation:
Split it up into a top rectangle and a bottom rectangle. Find the area of the top rectangle and subtract the combined area of the two quarter circles.
The area of the rectangle is 6 * 3 = 18. The area of the two quarter circles is the same as the area of one semicircle, and since the radius is 3 you can do:
3^2 * pi / 2 = 9pi/2. As a decimal this would be: 14.14.
Then, you can do rectangle - circle = 18 - 14.14 = 3.86. Rounded to the nearest tenth, this is 3.9
Answer:
It is necessary to stack 277778 dimes
Step-by-step explanation:
The height of the Empire State building in meters is 1250 * 0,30 = 375 meters. In mm such height is 375 * 1000 = 375000 mm
Finally 375000 / 1,35 = 277778
We have by distributivity of limits over sums, and continuity of
