To find the circumference of the can, we need to find the circumference of the top of the can (since the top and bottom have the same diameter) which is the same as the circumference of a circle with a diameter of 7 cm.
The formula for the circumference of a circle is C = πd, where d is the diameter.
In this case, the diameter is 7 cm. Plugging this value into the formula, we have:
C = 3.14 * 7
C = 21.98 cm
Rounding this to the nearest hundredth of a cm gives us a circumference of approximately 21.98 cm.
So, the correct answer is 21.98 cm.
