Johnny wrapped a piece of string around a can of soup. If the soup's diameter was 4 inches, how long was the string? Find the circumference

Answer:
12.56
Step-by-step explanation:
Formula is Pi* radius(squared) and since you aren't given the radius you can figure that out by dividing the diameter by 2 to get radius
Answer:
12.57 inches
Step-by-step explanation:
A piece of string wrapped around a can has the length of the circumference of the can.
circumference = pi * d
C = 3.14159 * 4 inches
C = 12.57 inches
