Answer: The Circumference is 9
Step-by-step explanation:
To find the circumference, need this formula:
[tex]c=2\pi r[/tex]
-Place the measurement of the radius onto that equation:
[tex]c=2\pi 4.5[/tex]
Then, you solve:
[tex]c=2\pi 4.5[/tex]
[tex]c=2[/tex] × [tex]\pi[/tex] × [tex](4.5)[/tex]
[tex]c=9[/tex] × [tex]\pi[/tex]
[tex]28.27[/tex]
-Round up to the nearest tenth
[tex]28.3[/tex]
