The surface area of a cylindrical can is equal to the sum of the area of two circles and the body of the cylinder: 2πr2 + 2πrh. volume is equal to π<span>r2h.
V = </span>π<span>r2h = 128 pi
r2h = 128
h = 128/r2
A = </span><span>2πr2 + 2πrh
</span>A = 2πr2 + 2πr*(<span>128/r2)
</span>A = 2πr2 + 256 <span>π / r
</span><span>
the optimum dimensions is determined by taking the first derivative and equating to zero.
dA = 4 </span>πr - 256 <span>π /r2 = 0
r = 4 cm
h = 8 cm

The correct answer is B) No, because there is not a fixed number of trials.

Answer:
1.01*10^-4
Step-by-step explanation:
first nonzero digit is 4 places to the right of the decimal point
.000<u>1</u>01
move decimal point 4 places to the right
1.01
multiply by 10^-4 since it was 4 places to the right
1.01*10^-4
