Answer:
92000
Step-by-step explanation:
Since you are asking in 534 minutes, that means it will double twice.
23000 * 2 * 2 = 92000
V = πr²h
V = (3.14)(5)²(16)
V = (3.14)(25)(16)
V = 1256
Hope this helps :)
I'm pretty sure it's 29 . . . A way to remember is that when you multiply a number by ten, add a zero. For example, 34 x 10 is 340. Just add the zero!
13 is 141. A octagon has 1080 degrees and if you add all the angles up you get 939 and 1080-930=141
