Answer:
12.56
Step-by-step explanation:
The formula of a circle's circumfernce is C = d pi
so we know that r = 2 and d = 2r
d then = 2 * 2 = 4
4 * pi (taking 3.14) = 12.56
therefore circumfernce = 12.56
104 square yards
The formula for area of a rectangle is length times width.
A = length x width
A = 13 x 8
A = 104
Since the units on each side are yards, the area is in square yards.
The height of the telephone pole = 9 / 1.5 = 6 meters
Divide 40 by 8 minutes to find the quantity per minute for one machine:
40 / 8 = 5 per minute.
One machine does 5 envelopes per minute.
Now divide 120 by 5 to find the number of machines needed:
120 / 5 = 24
24 machines would be needed.
3 and 4 is the answer for this
