The square root of 39 is 6.245. It lies between the whole numbers 7and 8!
Step-by-step explanation:
The given word problem can be transformed into Mathematical form as given below:

1002
The equation ( x + 1 ) + ( x + 2 ) + ( x + 3) = 3009
We do 1 + 2 + 3 = 6
Subtract 3009 with 6 = 3003
We have 3x = 3003
Divide 3003 / 3 = 1001
x = 1001
Let's use our equation!
1002 + 1003 + 1004 = 3009
Given:
The diameter of a circle = 20 feet
To find:
The exact circumference of the circle.
Solution:
We know that the radius is half of the diameter of the circle.
The diameter of a circle is 20 feet. So, the radius of the circle is 10 feet.
The circumference of the circle is:

Where, r is the radius.
Substituting
, we get



Therefore, the exact circumference of the circle is 62.8 feet.
Note: All options are incorrect.
