Hello!
2.5 litres = 1,000 * 2.5 = 2,500 cubic cm
volume = π * radius2 * height
2,500 = π * r2 * 20
2,500 / 20π = r^2
(Square Root of) 2,500 / 20π = r^2
6.307 <span>centimeters </span>= r (Radius)
Hope this Helps! Have A Wonderful Day! :)
They are symmetric on the y axis
The answer is class intervals. A big set of data are grouped into different classes to get a hint of the distribution, and the range of such class of data is known as the Class Interval. In other words, these are range of scores in a group frequency distribution. Class intervals are commonly equal in width and are mutually exclusive. The middle of an interval is called a class mark and the ends of a class interval are called class limits. To calculate the class interval, divide the range by the number of classes.
Answer:
so sorry i don't know the answer
Answer: 72
Step-by-step explanation: so you do a line = line method the lines should look like they are fractions.
you do it for the both numbers the percent is always out of 100.
it should look like this
40% ?
--------- = -----------
100% 180
then you cross multiply 40 and 180 and than divide it by 100. your answer should be 72. you later replace the ? with 72
you know this because It is smaller than 180 and its bigger than the number 40.
