The answer should be A. 4 Meters
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

Answer:
Area of a triangle is base times height divided by 2. The formula for finding the area of a parallelogram is easiest to just break it down into two triangles and 1 square/rectangle. Then just find the area of all then add them together to get the final area.
The statements about the hyperbola are true are:
- The center is located at (0, 0).
- There is a vertex at (–6, 0).
- The directrices are vertical lines.
<h3>What is a hyperbola?</h3>
It should be noted that a hyperbola simply means a open curve that has two branches.
Here, the center is located at (0, 0), there is a vertex at (–6, 0), and the directrices are vertical lines.
