Step-by-step explanation:

Surface Area:

A=2πrh+2πr^2

A=(2 * 3.143 * 8 * 8) + (2 * 3.143 *(8)^2)

A=402.286 + (2 * 3.143 * 64)

A=402.286 + 402.286

A line with a slope of -1 passes through the point (2,-1). If (-4, p) is another point on the line,

Thepotemich [5.8K]

$(\stackrel{x_1}{2}~,~\stackrel{y_1}{-1})\qquad (\stackrel{x_2}{-4}~,~\stackrel{y_2}{p}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{p}-\stackrel{y1}{(-1)}}}{\underset{run} {\underset{x_2}{-4}-\underset{x_1}{2}}}~~= ~~\stackrel{\stackrel{m}{\downarrow }}{-1}\implies \cfrac{p+1}{-6}=-1\implies p+1=6\implies p=5$
