Step-by-step explanation
you are fine, but you just need to multiply what you got by 150 in order to get the total number of radios made by all 150 employees.
Answer:
The point N lies inside the circle
Step-by-step explanation:
A circle is centered at the point T(-6,3) and has a radius of r=1.
To determine if the point N(3,-3) is inside or outside the circle, the distance between N and the point T must be lower than 11.
To calculate the distance between points T and N you use:
![d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
where x1 and y1 are the coordinates of T, and x2 and y2 the coordinates of N.
![d=\sqrt{(3-(-6))^2+(-3-3)^2}=\sqrt{9^2+6^2}=10.81](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%283-%28-6%29%29%5E2%2B%28-3-3%29%5E2%7D%3D%5Csqrt%7B9%5E2%2B6%5E2%7D%3D10.81)
d < 11
The distance d is lower than the radius of the circle. Hence, the point N lies inside the circle

Answer:
2419.0265 meters
Step-by-step explanation:
To find the answer you must first find the circumference of the circle. The circumference formula is C = 2 \pi r. So if you plug in 77 you get 483.8053. Then multiply that by 5 and you will have your final answer.
