The formula for radius is 
.
First we need to see what 8*π is, put it in your calculator and you will get . So now we know the exact circumference, so now put that into the equation to find the radius.
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY!

65%
There are only 7 numbers that don't fit this criteria. Therefore, there are 13 that do. 13/20 = .65*100 = 65%
I feel you man, I feel you.
6*1=6
4*8=32
2*4=8
32+8+6=46. B is 46 square cm.
9*2=18
10*2=20
1*2=2
18+2+20=40. Shape D is 40 cm.
4*5=20
3*4=12
1*3=3
12+3+20=35. C is 35 cm.
5*2=10
2*5=10
2*2=4
10+10+4=24 E is 24 cm.
Hope this helps! :D

Step-by-step explanation:
The question in English is
During the week 72 children will visit the park. For each child is prepared a rectangular box, in which to arrange what will be collected during the visit. Each box is 18 cm long and 12 cm wide. How long is the strip of cardboard that is used to make the edge of all boxes.
Let
x ----> the length of the box
y -----> the width of the box
we know that
The perimeter of the box is equal to
we have
step 1
Find the perimeter of one box
step 2
Find the perimeter of 72 box
Multiply the perimeter of one box by 72
Convert to meters
Divide by 100
Answer:
12 - 6 x (0 + 15) = 34
How I got my answer
First, how i got my answer was that I had to solve the equation first, ignoring the answer. I got 0 x 6 = 0, then I did 124 - 0 = 124, then I did 124 - 15 = 109, which clearly isn't 34. I figured that we have to put the parentheses around the zero because if we don't, we are going have to multiply something by zero, which always gets zero. After that, I decided that I should put the parentheses around either the 6, or the 15. I did both, and saw which one was correct. If we put it around the 6, we get, 124 - (6 x 0) + 15 = 124 - 0 - 15 = 124 - 15 = 109, which isn't 34. Then I checked 124 - 6 x (0 + 15) = 124 - 6 x 15 = 124 - 90 = 34, and we just got the answer.
P.S. Sorry if it was confusing, I didn't really know how to explain it
