The answer to 685 divided by 49 = 13.979
For that case the new circumference is:
C = 9 - 2
C = 7 inches
By definition, the circumference is:
C = 2 * pi * r
Where,
r: radio
Substituting values:
7 = 2 * pi * r
Clearing the radio:
r = 7 / (2 * pi)
Then, the diameter is:
d = 2 * r
Substituting:
d = 2 * (7 / (2 * pi))
d = 2.228169203
Round to the hundredth:
d = 2.23 inches
Answer:
The diameter of the roll after the decrease is:
d = 2.23 inches
If you are asking for the answer the answer is 0.67.
Answer:
Step-by-step explanation:
8 ft by 4 ft
8ft x 4ft = 32 ft
8ft + 8 ft = 16 ft 4 ft + 4 ft = 8 ft
16ft + 8 ft = 24 ft
