To multiply 9x475 using expanded form and the distributive property, you will break 475 into three numbers, multiply each of them by 9, and add the products together:
475 = 400 + 70 + 5
400x9 = 3600
70x9 = 630
5x9 = 45
3600 + 630 + 45 = 4,275
General form for circle is
(x - a)^2 + (y - b)^2 = r^2
so if center is at (3,-2) we can plug in a and b:-
(x-3)^2 + (y+2)^2 = r^2
Now plug in x = 7 and y =1 (from the point R)
4^2 + 3^2 = r^2
r^2 = 25 making r = 5
so its diameter = 2*5 = 10
I'm not 100% sure, as we don't do this at school here, but I think its :
1) 3 units right, 2 units down
2) (x, y) > (x-12, y+3)
3) (x, y) > (x+9, y-8)
