Material=wall+2*side and material is 40 ft so:

40=w+2s

w=40-2s

Area=ws, using w from above we get:

A=(40-2s)s

A=40s-2s^2

dA/ds=40-4s and d2A/ds2=-4

Since d2A/ds2 is a constant negative acceleration, when dA/ds=0, A(s) is at an absolute maximum.

dA/ds=0 when 4s=40, s=10 ft

And since w=40-2s, w=20 ft

So the dimensions of the pen are 20 ft by 10 ft, with the 20 ft side being opposite the wall.  And the maximum possible area is thus 200 ft^2

Answer:

The <em>dimensions</em> are 20 ft by 10 ft.

Step-by-step explanation:

I just took this quiz and put the answer 200 by 200 ft. And I got it wrong because they asked for the dimensions. The other person's answer is correct, but in the wrong form! Thanks for the help and support on brainly!!!

What is the volume of a cylinder in cubic ft with a height of 14ft and a base diameter of 12ft round to the nearest tenth
pishuonlain [190]

Answer: volume of the cylinder = 1583.36 ft3

Step-by-step explanation: where volume of a cylinder = π h

where h = 14 ft

diameter 12 ft, so radius = 12 / 2 = 6 ft

therefore volume = π * * 14 = 1583.362697 to the nearest tenths place will be 1583.36
