Question

A jar lid has a diameter of 32

millimeters. What is the
circumference of the lid to the
nearest tenth?

Answer 1

32pi cm or 100.530964915 mm

Explanation:

To find this answer you will need to use the equation 2*pi*r or pi*d.

Your value 32 can be plugged in as your value of d which can then be substituted to make 32 pi or if you use a calculator you get 100.530964915.

hope this helps!

Answer 2

Answer: 100.5 mm

Step-by-step explanation: The formula to find the circumference of a circle is 2(pi)r

Since we know the diameter is 32, divide 32 by 2 to get the radius: 16

2(pi)(16) = 100.5309

To the nearest tenth, that would be 100.5
