All you needed to do was write down the formula for the circumference on a circle, which is what? Then fill in the blank and solve.
To find the circumference of a circle, you can use the formula:
C = πd
where C is the circumference and d is the diameter.
In this case, the diameter of the juice glass base is given as 5 centimeters. So, we can plug this value into the formula and calculate the circumference.
C = 3.14 * 5
C = 15.7 cm
Therefore, the closest option to the circumference of the base of the juice glass is A. 15.7 cm.
