Answer:
16.9 m
Step-by-step explanation:
Start with a half a circle. The central angle of a semicircle is 180 deg.
Now subtract 21 deg on each side.
180 - 21 - 21 = 138
The central angle is 138 deg.
The radius is 7 m.
Now we use the formula for the length of an arc of a circle given the radius of the circle and the central angle of the arc.
![s = \dfrac{n}{360^\circ}2 \pi r](https://tex.z-dn.net/?f=%20s%20%3D%20%5Cdfrac%7Bn%7D%7B360%5E%5Ccirc%7D2%20%5Cpi%20r%20)
![s = \dfrac{138^\circ}{360^\circ}2(3.14159)(7~m)](https://tex.z-dn.net/?f=%20s%20%3D%20%5Cdfrac%7B138%5E%5Ccirc%7D%7B360%5E%5Ccirc%7D2%283.14159%29%287~m%29%20)
![s = 16.9~m](https://tex.z-dn.net/?f=%20s%20%3D%2016.9~m%20)
The fraction 3/9 is equivalent to 1/3.The fraction 3/9 is equal to 3÷9 and can also be expressed in decimal form as 0.333333.
