ANSWER
The approximate circumference is 377 inches
Step-by-step explanation
The circumference of a circle is calculated using the formula
![C=2 \pi \: r](https://img.qammunity.org/2020/formulas/mathematics/middle-school/8y5p6k46yze9991pypmty33p8niybtxh1y.png)
Where r=60 inches is the radius of the circle.
We substitute π=3.4 and the radius into the formula to obtain:
![C=2 (3.14)(60) \: inch](https://img.qammunity.org/2020/formulas/mathematics/middle-school/73737vkigfflmiwvjv02fr6i7xvh3a0txn.png)
![C = 376.8inches](https://img.qammunity.org/2020/formulas/mathematics/middle-school/g93voisqhhk7qodne9qt3iuvf3x7hcx1xb.png)
The approximate circumference of the circle is 377 inches.
