Well, first you need to decide what place you want to round it TO.
Example: Round it to the nearest hundredth:
The next larger hundredth is 186.29 .
The next smaller hundredth is 186.28 .
Now look at it.
186.282 is closer to 186.28 than it is to 186.29 .
So the nearest hundredth is 186.28 .
-- When 186.282 is rounded to the nearest hundredth, it becomes 186.28 .
Similarly . . .
-- When 186.282 is rounded to the nearest tenth, it becomes 186.3 .
-- When 186.282 is rounded to the nearest whole number, it becomes 186 .
-- When 186.282 is rounded to the nearest ten, it becomes 190 .
-- When 186.282 is rounded to the nearest hundred, it becomes 200 .
-- When 186.282 is rounded to the nearest thousand or anything larger,
it becomes zero.
I'm curious . . . where did this number come from ?
It happens to be one thousandth of the speed of light, in miles per hour.
Did it come up in science class, or did a science geek use it for
one of the problems in math ?
3,276.8 cm^3 or 32.768 m^3
It is already simplified because there is nothing you can divide into both 18 and 25 that would result in whole numbers.
The formula for this is
. If the diameter is 8 the radius is 4, so filling in accordingly we have
and
which is
and when you multiply in 3.14 you get that A = 401.92 or B above.
