Answer:
7.85 cm
Step-by-step explanation:
The circumference of a circle can be found using the following formula.
[tex]c=\pi d[/tex]
The diameter is 2.5 centimeters. Therefore, we can substitute 2.5 cm in for d.
[tex]c=\pi *2.5 cm[/tex]
Now, find the circumference.
- In terms of pi:
[tex]c=\pi *2.5 cm[/tex]
[tex]c= (2.5)\pi cm[/tex]
[tex]c= 2.5\pi cm[/tex]
-Using 3.14 as pi
[tex]c=\pi *2.5 cm[/tex]
[tex]c=3.14 *2.5 cm[/tex]
[tex]c=7.85 cm[/tex]
-Using 3.14159... as pi
[tex]c=\pi *2.5 cm[/tex]
[tex]c=7.85398163 cm[/tex]
