Answer:
V=7982.4 in
Step-by-step explanation:
V=4/3pi*r^3
V=4/3pi*12.4^3
V=4/3pi*1906.62
V=7626.48/3pi
V=2542.16pi
V=2542.16*3.14
V=7982.4
4 1/5 - 2/3
Turn 4 1/5 into an improper fraction.
5x4+1= 21/5
21/5 - 2/3
Multiply 5 and 21 by 3 and 3 and 2 by 5 to get the same denominator.
63/15-10/15=53/10
Turn the improper fraction into a mixed number by dividing the 53 and 10.
Answer: 5 3/10 or five and three tenths
An ordered pair (x, y) represents a position of a point on a coordinate graph, where x is the number on the x-axis that the point lines up with and y is the number on the y-axis that the point lines up with. The numbers x and y in the ordered pair (x, y) are called coordinates
i hope this is what you meant
The nearest hundred will be in the hundredth place
For example, 2000
2 is in the thousands, followed by hundreds, ten, ones
to round to the nearest hundreds, you must look at the tens place (in this case 7) IF it is 5 or higher round the hundreds 1 number higher (+1) If it is 4 or lower, round all of the numbers including the number you are looking at to zero without changing the one in front of it.
So in this case 678 will equal 700
Example: if it were 644, then it would be 600
hope this helps
