A=1/2 * d1 * d2
a=1/2 * 2.7 * 3.2= 4.32mm

Answer:</h2>
<h3>container B requires more plastic to make.</h3>
<h2>
Step-by-step explanation:</h2>
Container A:
diameter- 7 cm
height- 122 cm
radius- 3.5 cm
<h3>calculating for the surface area</h3>
SA=2×π×r×r+2×π×r×h
SA=2(3.14)(3.5)(3.5)+2(3.14)(3.5)(122)
SA=76.93+2681.56
SA=2758.49 cm^2
<h3>Container B:</h3>
diameter- 11 cm
height- 85 cm
radius- 5.5 cm
<h3>calculating for the surface area</h3>
SA=2×π×r×r+2×π×r×h
SA=2(3.14)(5.5)(5.5)+2(3.14)(5.5)(85)
SA=189.97+2935.90
SA=3125.87 cm^2
<h3>Container B required more plastic to make</h3>
5-(-1) or you could simplify it further to 6
The formula for a cone shaped object for volume is volume= 3.14 times the radius to the second power times height/three so your formula will be
v=3.14*3^2*4.5/3...............your answer will be 42.41
