Answer:
The circumference appears four times larger.
Step-by-step explanation:
C=2πr
So if we are multiplying the radius (r) by 4 then that would most definitely increase the outcome (circumference) by 4
here's why:
C=2πr
C=2π(4r)
C=8πr
So,
8πr/2πr = 8/2 = 4
Hope this helps! ;)
The graph of the line segment PQ is attached. To find the length, we have to use distance formula which is
![d = \sqrt{ (x_{2} -x_{1} )^2 + (y_{2} - y_{1} )^2 }](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B%20%28x_%7B2%7D%20-x_%7B1%7D%20%29%5E2%20%2B%20%28y_%7B2%7D%20-%20y_%7B1%7D%20%29%5E2%20%20%7D%20)
![PQ = \sqrt{ (2-(-2))^2 + (4- (-1))^2 } = \sqrt{ (2+2)^2 + (4+1)^2 }](https://tex.z-dn.net/?f=%20PQ%20%3D%20%5Csqrt%7B%20%282-%28-2%29%29%5E2%20%2B%20%284-%20%28-1%29%29%5E2%20%7D%20%3D%20%5Csqrt%7B%20%282%2B2%29%5E2%20%2B%20%284%2B1%29%5E2%20%7D%20)
![PQ = \sqrt{16+25} = \sqrt{41}](https://tex.z-dn.net/?f=%20PQ%20%3D%20%5Csqrt%7B16%2B25%7D%20%3D%20%5Csqrt%7B41%7D%20)
To find the midpoint,we have to use the formula
![( \frac{x_{1}+ x_{2} }{2} ,\frac{y_{1}+ y_{2} }{2} ) = (\frac{-2+2}{2} , \frac{-1+4}{2} )](https://tex.z-dn.net/?f=%20%28%20%5Cfrac%7Bx_%7B1%7D%2B%20x_%7B2%7D%20%7D%7B2%7D%20%2C%5Cfrac%7By_%7B1%7D%2B%20y_%7B2%7D%20%7D%7B2%7D%20%29%20%3D%20%28%5Cfrac%7B-2%2B2%7D%7B2%7D%20%2C%20%5Cfrac%7B-1%2B4%7D%7B2%7D%20%29%20)
![= ( \frac{0}{2} , \frac{3}{2} ) = (0 , \frac{3}{2} )](https://tex.z-dn.net/?f=%20%3D%20%28%20%5Cfrac%7B0%7D%7B2%7D%20%2C%20%5Cfrac%7B3%7D%7B2%7D%20%29%20%3D%20%280%20%2C%20%5Cfrac%7B3%7D%7B2%7D%20%29%20)
