700pi+2000. First calculate the area of the two straight shaded region. Each of them is 10 m wide and 100 m long, so their total area is 2*10*100=2000 m^2. Then calculate the curved regions, each of which is equal to the area of the bigger half circle minus small half circle, which is 1/2*pi*[(60+10+10)/2]^2-1/2*pi*(60/2)^2=350 pi m^2, so the total area is 2*350pi+2000 m^2=700pi+2000.
If a triangle is inscribed in a circle, and its hypotenuse is the diameter, it is automatically a right triangle.
Using the Pythagorean theorem, (diameter AB)^2 = (AC)^2 + (BC)^2
AB^2 = 144 + 25 = 169
AB = 13
Therefore the radius is 13/2 = 6.5 units.
To answer to the question above, when adding or subtracting measurements (numbers), the result must have the same number of decimal places as the number in the problem with the fewest decimal places.
<span>24.545 + 307.3 = 331.845</span>
However, the answer must be given to the correct number of decimal places, in this case, 1 in 307.3.
So the result of the addition of 24.545 and 307.3 should be 331.8.
Answer:
(a)
(b)
(c)43 times
Step-by-step explanation:
<u>Part A</u>
The paper's thickness = 0.05mm
When the paper is folded, its width doubles (increases by 100%).
The thickness of the paper grows exponentially and can be modeled by the function:
<u>Part B</u>
<u /><u />
<u />
<u>Part C</u>
If the thickness of the paper, g(n)=384,472,300,000 mm
Then:
You must fold the paper 43 times to make the folded paper have a thickness that is the same as the distance from the earth to the moon.
