Answer:
648pi
Step-by-step explanation:
V=pi*r^2*h
V=pi*9^2*8
V=pi*81*8
V=648pi
If the perimeters are equal, you can form an equation to find x:
x + x + 12 + x + x + 12 = x + 11 + x + 11 + x + 16
4x + 24 = 3x + 38
- 3x
x + 24 = 38
- 24
x = 14
Now you can substitute the x value into the perimeter:
(4 × 14) + 24
56 + 24 = 80 cm
(3 × 14) + 38
42 + 38 = 80 cm
So the perimeter would be 80 cm.
I hope this helps!

the answer is 0.24 jjjjjjjjjjjjjj
Perimeter = x + 5x - 2 + 7x - 4
= 13x - 6 meters answer
Well, volume is: length x width x height
so, 5 x 14 x 8= 560 inches
