Answer:
C≈90
Step-by-step explanation:
remember circumference formula
[tex] \displaystyle C = 2\pi r[/tex]
given that,r=15 thus substitute:
[tex] \displaystyle C = 2\pi .15[/tex]
simplify mutilation:
[tex] \displaystyle C = 30\pi [/tex]
substitute the given value of π:
[tex] \displaystyle C = 30.3[/tex]
simplify multiplication:
[tex] \displaystyle C = 90[/tex]
and we are done!
