Solution :
Given a soda can has a diameter of 6 cm.
As we know, the circumference of circle with radius r is , [tex]C=2\pi r[/tex].
And diameter of the circle [tex]D = 2r[/tex]
So, the circumference of the circle with diameter D is , [tex]C=\pi D[/tex]
Put D= 6
[tex]\Rightarrow C=6 \pi\\\\Using\: \pi=3.14\\\Rightarrow C=6\times3.14\\\\\Rightarrow C=18.84[/tex]
Hence, the circumference of the can is 18.84 cm. (option C)
