Find the circumference of the circle (it says 2.5 with a little dot, I don't know what it means and the lesson wasn't very helpful...please help me :( thank you to whoever is reading this and I hope you have a great day) Round your answer to the nearest centimeter.
What is 2.5 with a little dot?
is the radius 2.5 ?
C = 2πr = 5π cm , use your calculator
Thank you, but that makes 0 since to me :')
Your problem doesn't seem to make sense to Reiny, an long-experienced math tutor. (It doesn't make sense to me either.) Do you possibly have an error in the problem???
It’s a little dot with a line coming from it, measuring from the middle to the side of the circle, the measurement is 2.5 cm. And it asks to find the circumference. Round to the nearest centimeter. We/I need help!
To find the circumference of a circle, we use the formula C = 2πr, where C represents the circumference and r represents the radius of the circle.
In your question, you mentioned that there is a "2.5 with a little dot," which indicates that the radius of the circle is 2.5 units.
Now, let's substitute this value into the formula and calculate the circumference.
C = 2πr
C = 2π(2.5)
First, let's calculate the value of π (pi). Pi is an irrational number with an approximate value of 3.14.
C = 2(3.14)(2.5)
C = 6.28(2.5)
C = 15.7
The calculated circumference of the circle is 15.7 units.
Since you mentioned rounding to the nearest centimeter, we need to convert the units from the given units (which are uncertain) to centimeters. If the units are already in centimeters, then no conversion is required.
If the units are not in centimeters, please provide the given units, and I can help you convert them to centimeters using the appropriate conversion factor.
