Do you have to find the angle or the measurement?
The answer is <span>(x, y)→(x - 9, y - 3)
proof
according to the figure H (3, -1) and H' (-6, -4)
</span><span>-6= 3 -9, and - 4= -1 -3, </span>
Well plug 0 in for x and solve for y and that is the vertex of your expression
A=226.19 A=2πrh+2πr2=2·π·4·5+2·π·42≈226.19467
