the area of a circle is A = πr², where r = radius of the circle.
how to find points in the circle? depends on what the scenario is, if you know circle's center and its radius, simply use the distance formula to get any of the points, if you have only the equation of it in standard form, you can use the x,y coordinates with substitution, if you have an sketch, you can get them off the grid, so depends on what you have as components.

Answer: My bad if I butchered any answers. It was hard to read tbh
Step-by-step explanation:
D.) You can only factor out an x here. So you'd get: 
E.) You can factor out a 3x^2y to get: 
F.) You can factor out a 3xy to get: 
G.) You can factor out a -4ab to get: 
Answer:
800 months
Step-by-step explanation:
The formula for interest is:
(Capital * saving account * time) / 100
So:
(10000 * 0.06 * x) / (100) = 4800
We clear x:
(10000 * 0.06 * x) = (100) * 4800
x = 480,000 / (10000 * 0.06)
x = 800 months (66.67 years)
