Answer:
308 mm
Step-by-step explanation:
The formula for circumference of a circle is [tex]C=2\pi r[/tex]
Where C is the circumference
[tex]\pi[/tex] is [tex]\frac{22}{7}[/tex], and
r is the radius (given as 49)
Putting them into the formula, we get:
[tex]C=2\pi r\\C=2(\frac{22}{7})(49)\\C=308[/tex]
Thus, circumference = 308 mm
