i need help with this.find the circumference circle. Use 3.14 or 22/7 for π

Given a circle with diameter D, the circumference, C, is given by:
[tex]C=\pi\times D[/tex]In this case D = 14 / 15 in.
Therefore
[tex]C\text{ = 3.14 }\times\frac{14}{15}=\frac{43.96}{15}=2.93in[/tex]Hence the circumference is 2.93 inches
