A dog's chew toy is a rubber ring with a circumference of 41 cm. What is the diameter of the chew toy, rounded to the nearest centimeter? Use 3.14 to approximate pi. cm

The circumference is defined as the multiplication of pi times the diameter, so we have:

c = pi*d

where c is the circumference and d the diameter, if we solve for d:

d = c/pi

and substitute our dа ta:

d = 41/3.14

d = 13.06 cm

that is the diameter
