\text{Hello there!}\\\\\text{We're trying to find the circumference}\\\\\text{We know that the diameter is 100}\\\\\text{We would use the equation:}\,C=2\pi r\\\\\text{The radius is half of the diameter, so the radius would be 50}\\\\\text{Plug 50 into r}\\\\C=2\pi (50)\\\\\text{Solve:}\\\\C=2\pi (50)\\\\C=2(157)\\\\C=314\\\\\large\boxed{C=314\,\,m}\\\\\text{I hope this helps!}\\\text{Best regards,}\\\text{MasterInvestor}
