The answer is 350.
<em>
m= minutes</em>

Plan 1:  9+0.13<em>m</em>
Plan 2:  23+0.09<em>m</em>

9+0.13<em>m</em> = 23+0.09<em>m</em>
-9               -9
0.13<em>m</em> = 14+0.09<em>m</em>
-0.09<em>m</em>        -0.09<em>m</em>
0.04<em>m</em>= 14
14÷0.04= 350
<em>m</em>= 350

koban [17]

Answer:

1526.0 cubic units

Step-by-step explanation:

Rotating rectangle AKLM you will get cylinder with height KA and base radius KL.  From the given data

KA=\sqrt{(6-0)^2+(0-0)^2}=6,\\ \\KL=\sqrt{(0-0)^2+(9-0)^2}=9.

The volume of the cylinder is

V_{cylinder}=\pi r^2\cdot H.

Then

V_{cylinder}=\pi \cdot 9^2\cdot 6=486\pi \approx 1526.0\ un^3.
