Answer:Wednesday I think
Step-by-step explanation:
Formula for Volume of Cylinder you need the radius
To estimate, round 3102 to 3100
round 1-10 to 2500
1-70 to 2100
1-80 to 2900
2900+2100+2500+3100=10600mi
Yes it is reasonable because you add and subtract numbers when estimating, however it is not exact
