Answer:
8/π
Step-by-step explanation:
Volume of the cylinder is:
V = πr²h
Surface area of the cylinder (with square top and bottom) is:
A = 2πrh + 8r²
Use the volume equation to write h in terms of r.
h = V / (πr²)
Substitute into the area equation:
A = 2V / r + 8r²
Take derivative with respect to r.
dA/dr = -2V / r² + 16r
Set to 0 and solve for r.
0 = -2V / r² + 16r
2V / r² = 16r
2V = 16r³
V = 8r³
Plug into the volume equation.
8r³ = πr²h
8r = πh
h / r = 8 / π
Answer:
Ben's error is that he thought both pizzas were the same size, well what was left and in the beginning.
Step-by-step explanation:
Even if both 1/4 is left, that doesn't mean you started with the same amount. Also, both 1/4 pieces are different shapes and sizes, making him wrong.
Hope this helped!! :)
Math Sucks hahahahahahahahahahahahaha
