When baking a cake, you have a choice of the following pans:
a round cake pan that is 2 inches deep and has a 7 inch diameter
a 6 inch × 9 inch rectangular cake pan that is 2 inches deep
a. Which of these pans has the larger volume? Justify your answer.
b. Excluding the bottom of the cake, what is the surface area of each cake that will be covered by
frosting? Justify your answer.
I just need help with b
Steve answered: volumes are
round: πr^2h = π*(7/2)^2*2 = 98π/4 = 76.969 in^3
parallelopiped: LWH = 6*9*2 = 108 in^3
should be easy to tell now, eh?
areas are
round: πr^2 + 2πrh = πr(r+2h)
brick: LW+2LH+2WH = LW+2H(L+W)
Now plug in your numbers and compare
Then I asked: So...
Area for round pan: 3.14*3.5*2+2*3.14*3.5*3.5=98.91
and...
Area for rectangular pan:
9*6+2*9*2+2*6*2=114
Am I right if not help me with b

It's literally one month away from the end of the year, do you think any of these people give a damn if they're kicked out at this point?
Homeschool is literal garbage, it's lonely and horrible and honestly, if I got kicked out that's just one month of work that I don't have to do before I go to an actual school.
How thick is your skull my duuude?
