A can manufacturing company is designing a can of cat food to hold 5.5 oz or about 163 cm(3). They have written out that the equation for the surface area for a can with the volume is S=2pie radius(2) + 163/r. Explain why the equation is wrong and how to fix it.

The correct equation that describes the surface area is and we need to multiply by 2 in the equation described in the statement to correct the equation.

Step-by-step explanation:

Let suppose that the can of cat food is a right cylinder. The surface area of the cylinder (), measured in square centimeters, is the sum of the areas of the circular walls () and the non-circular wall (), both measured in square centimeters. That is:

(1)

By Geometry, we expanded the equation above:

(1b)

Where:

- Radius, measured in centimeters.

- Height, measured in centimeters.

And the volume of the right cylinder (), measured in cubic cnetimeters, is defined by the following formula:

Then, we clear the height of the cylinder within the volume formula:

(2)

By substituting in (1b), we obtain the following equation:

(1c)

If we know that , then the equation for the surface area of the cylinder is:

In a nutshell, we need to multiply by 2 to correct the equation.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
