Answer:

D : 3456

Step-by-step explanation:

Use the formula 'volume of a cylinder' which is V = πr^2h

Since you know that the diameter is 20m and you need the radius, the radius is half the diameter, 10m. The height would be the length of the cylinder which is 11m.

Hence π10^2(11). If you put that in the calculator you get 3455.75, round it up and you 3456, answer D

Y = mx + b to find the equation of the line that passes through the points (−6, 1) and (3, 4).

Luda [366]

$\bf (\stackrel{x_1}{-6}~,~\stackrel{y_1}{1})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{4}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{4}-\stackrel{y1}{1}}}{\underset{run} {\underset{x_2}{3}-\underset{x_1}{(-6)}}}\implies \cfrac{3}{3+6}\implies \cfrac{3}{9}\implies \cfrac{1}{3}$

$\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{1}=\stackrel{m}{\cfrac{1}{3}}[x-\stackrel{x_1}{(-6)}] \implies y-1=\cfrac{1}{3}(x+6) \\\\\\ y-1=\cfrac{1}{3}x+2\implies y=\cfrac{1}{3}x+3$
