2. To find the center we require the midpoint of the 2 given points
center =![[\frac{1}{2}(-4-6),\frac{1}{2}(11+5)]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B1%7D%7B2%7D%28-4-6%29%2C%5Cfrac%7B1%7D%7B2%7D%2811%2B5%29%5D)
=(-5,8)
3. The radius is the distance from the centre to either of the 2 given points calculate the radius using the distance formula

3b + 9c = 3*b + 3* 3 *c = 3*(b + 3c)
We can break down the number 6647 into:
6647=6000+600+40+7
The first 6 in the number is in the thousands place (6,000), and the second 6 is in the hundreds place (600).
The first 6 is 10 times greater than the second one.
