➷ The formula to calculate the circumference is 
d is the diameter (double the radius)
Substitute the values in:
Circumference = (3.14)(3 x 2)
Circumference = 18.84
It would be option D. 18.84 m

Answer:
32
Step-by-step explanation:
The equation 
and the graph below describe the velocity V in feet per second of a ball <em>t</em> seconds after it is shot into the air.
To find the balls velocity after seven seconds, substitute t = 7 into the function expression:
Unlike fraction 1/7 is converted to equivalent like fraction 2/14 and the sum of 2/14 + 3/14 = 5/14.
As given in the question,
Given fraction is equal to:
1/7=? + 3/14=?
Here there are two fractions
1/7 and 3/14
LCD( least common denominator) of 7 and 14 is equal to 14.
Now make them like fractions
1/7 is equivalent to
( 1/7) × ( 2/2) = 2/ 14
Now 2/14 and 3/14 are like fractions
Sum of like fractions is:
2/14 + 3/14
= ( 2+ 3) / 14
= 5/ 14
Therefore, the conversion of unlike fraction 1/7 to like fraction is 2/14. And sum of 2/14 + 3/14 = 5/14.
The complete question is:
Convert these unlike fractions to equivalent like fractions and add them. You must use the LCD to get the answer correct. If possible, reduce the final sum. 1/7=? + 3/14=?
