The top of a cylindrical can has a diameter of 7 cm. What is the circumference of the van rounded to the nearest hundredth of a cm ? Use 3.14 for pi

1 answer

The radius of the top of the cylindrical can is half of the diameter, so it is 7 cm / 2 = <<7/2=3.5>>3.5 cm.
The circumference of the top of the can is 2 * pi * radius = 2 * 3.14 * 3.5 = 21.98 cm.
Rounded to the nearest hundredth, the circumference of the top of the can is 21.98 cm rounded to 21.99 cm. Answer: \boxed{21.99}.
