the radius of a circle is 5.5cm, what is the circumference in meters?
This is AP Physics?
C = pi * d
C = 3.14 * 11
C = 34.54 cm = 0.3454 m
Yes, this is AP physics. :)
Thanks Ms. Sue!
You're welcome, Lisa.
Oh, can you help me with some of my other AP work too? It's due in a week. Thanks, Ms. Sue.
I'm sorry, but I never took physics -- so most of your questions are way beyond me.
What about Biology? Are any of the other physics teacher online?
These are all like grade nine and ten questions. How can this possibly be AP physics?! If you think this course will prepare you for university physics you are in for a surprise. If you can't do questions this simple, you will fail... indefinitely.
i'm in ap physics too and we do WAY more complicated stuff than that.
To find the circumference of a circle, you can use the formula:
Circumference = 2 * π * radius
Given that the radius of the circle is 5.5 cm, we need to convert it to meters before calculating the circumference.
To convert centimeters to meters, divide the value by 100 (since 1 meter = 100 centimeters).
Converting the radius of 5.5 cm to meters, we have:
Radius in meters = 5.5 cm / 100 = 0.055 meters
Now, we can substitute this value into the circumference formula:
Circumference = 2 * π * 0.055 meters
Using the value of π (pi) as approximately 3.14159, we can calculate the circumference:
Circumference = 2 * 3.14159 * 0.055 meters
Circumference ≈ 0.345 meters
Therefore, the circumference of the circle with a radius of 5.5 cm is approximately 0.345 meters.
