Reason:
Formula for speed is speed =
, if you want to find time, then take distance / speed, which will equal to 100 / 20 = 5 hours, and the same with 2.

Answer:
A=2πrh+2πr2 this is the formula you'll need to answer your question!
Step-by-step explanation:
so what you'll do is basically just follow the formula above and fill in the numbers where they need to be.
The two numbers you need to fill in is r which is your radius, which in this case would be 6.
And h which is the height which is 9.
So the total formula now would be, A= 2xπ6x9+2xπx6x2
So your answer would be 565.49 cm or 565 pi cm (this depends on how your teacher wants you to write it.)
Hope this helps at all!!
Answer:
n-3≥-5
If you need the equation solved...
n-3≥-5
<u>+3 +3</u>
n≥-2
