Answer:
2640mm
Step-by-step explanation:
I'm assuming you need the area of the rectangle which the circles don't take up.
First, to find the area of the whole rectangle:
length x width
to find length:
the length is 1 circle, therefore it is the diameter of the circle, which is 32 x 2 = 64mm
to find width:
the width is 3 circles, which is the radius 6 times, so 32 x 6 = 192mm
So, area of rectangle = 64 x 192 = 12288mm
Now to find the area the circles take up:
area of 1 circle =

=

=

As we have 3 circles, we multiply this by 3:

Finally we subtract the area of the three circles from the area of the rectangle:

As we need to round it to 3 significant figures, the answer is 2640mm
<h2><em>9.07 > 9.008 is true </em></h2>
Answer:
1) ¼
2) yes
Step-by-step explanation:
1) P(A) = 13/52 = 1/4
P(B) = 4/52 = 1/13
P(A^B) = 1/52
P(A|B) = (1/52) ÷ (1/13) = 1/4
Since P(A|B) = P(A), they are independent
I think the correct answer from the choices listed above is the fourth option. The statement that is not true about David Hilbert would be that he wrote a biography on Euclid. Hope this answers the question. Have a nice day. Fee; free to ask more questions.
