A cylinder shaped can needs to be constructed to hold 400 cubic centimeters of soup. The material for the sides of the can costs

LenKa [72]

Answer:

The dimensions of the can that will minimize the cost are a Radius of 3.17cm and a Height of 12.67cm.

Step-by-step explanation:

Volume of the Cylinder=400 cm³

Volume of a Cylinder=πr²h

Therefore: πr²h=400

$h=\frac{400}{\pi r^2}$

Total Surface Area of a Cylinder=2πr²+2πrh

Cost of the materials for the Top and Bottom=0.06 cents per square centimeter

Cost of the materials for the sides=0.03 cents per square centimeter

Cost of the Cylinder=0.06(2πr²)+0.03(2πrh)

C=0.12πr²+0.06πrh

Recall: $h=\frac{400}{\pi r^2}$

Therefore:

$C(r)=0.12\pi r^2+0.06 \pi r(\frac{400}{\pi r^2})$

$C(r)=0.12\pi r^2+\frac{24}{r}$

$C(r)=\frac{0.12\pi r^3+24}{r}$

The minimum cost occurs when the derivative of the Cost =0.

$C^{'}(r)=\frac{6\pi r^3-600}{25r^2}$

$6\pi r^3-600=0$

$6\pi r^3=600$

$\pi r^3=100$

$r^3=\frac{100}{\pi}$

$r^3=31.83$

r=3.17 cm

Recall that:

$h=\frac{400}{\pi r^2}$

$h=\frac{400}{\pi *3.17^2}$

h=12.67cm

The dimensions of the can that will minimize the cost are a Radius of 3.17cm and a Height of 12.67cm.

THE HELP IVE BEEN RECIEVEING HAS MADE ME SO HAPPY SO I JUST WANNA TAKE THE TIME TO SAY THANK YOU SO MUCH T-T. if anyone can help

Alex Ar [27]

Answer:

Some answers to the reducing fraction sheet

Q14 = 4/5 because divide 12 and 15 by 3

Q15=can't be reduced because 11 is a prime number so it can't be divided by anything

Q17=can't be reduced because 17 is a prime number

Q18=can't be reduced because 13 is a prime number

Q19=38/9 because 114 and 27 would be divided by 3

Q20= -1/1 because you would divide both 14,529 by itself would equal to - 1/1

I can only help you with this sheet I can't help you with the other one hope this was helpful! :)
