Answer:
(x-2)^2+y^2=16
Step-by-step explanation:
If the center of the circle is (h,k) and the radius is r, then the equation of a circle is (x-h)^2+(y-k)^2=r^2 (with the Pythagorean theorem)
So, the center of this circle 0 is (2,0) and the radius is 4. Thus, the equation is (x-2)^2+y^2=16

Answer:
a) an expression for the number of groups formed by p people
number of groups formed = ![\frac{p}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bp%7D%7B4%7D)
b) How many groups are formed if there are 28 people
number of groups formed = ![\frac{p}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bp%7D%7B4%7D)
=28÷4
= 7
Answer: 7 groups
