A feeding trough was made by hollowing out half of a log. The trough is shaped like half a cylinder. It is 5 feet long and has an interior diameter of 1.5 feet. What is the volume of oats that will fill the trough?
Answers
Answer=4.18 feet³
The formula for the volume of a cylinder is:
V=πr²h
However, the cylinder in the problem is half cylinder, so we have to edit the formula to.
V=(πr²h)/2
Now lets plug in the information known...
diameter/2=radius 1.5/2=radius 0.75=radius
V=(π*0.75²*5)/2 V=(π*0.5625*5)/2 V=(π*2.8125)/2 V=(8.8357)/2 V=4.1785 feet³ round to the nearest hundredth V=4.18 feet³

Max delivers 8,520 pieces of mail in one year. If he delivers the same number of pieces of mail each month, about how many pieces of mail does he deliver in 2 months? Explain your steps.Can you help me and explain this question... Thanks!
Answers
So there are 12 months in a year and he delivers 8,520 in that time. You must divide 8,520 by 12 which gives you how many he delivers in one month. 8,520/12=710. You are looking for two months so you should then multiply 710 by two giving you how much he delivers in 2 months. 710*2=1,420 Max delivers 1,420 pieces of mail in two months

What is 152,909 rounded to the nearest hundred thousands
Answers
152,909 rounded to the nearest hundred thousands is 200,000.
Rules of rounding numbers 1) if the number being rounded off is followed by 0, 1, 2, 3, and 4, round the number down. 2) if the number being rounded off is followed by 5, 6, 7, 8, and 9, round the number down.
1 is the number on the hundred thousands place. It is followed by 5. We round 1 up to 2. Thus 2 is now in the hundred thousands place.
The answer is 200,000 because when you have 5-9 in the place value next to what your rounding to you go up a number in the place your rounding in and all the rest of the numbers behind the place value that your rounding in.
