How do i round 186.282?
adoni [48]

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 ?

What is the surface area of a cylinder with a diameter of 8 centimeters and a height of 12 centimeters?
Lostsunrise [7]
The formula for this is A=2 \pi rh+2 \pi  r^{2}.  If the diameter is 8 the radius is 4, so filling in accordingly we have A=2 \pi (4)(12)+2 \pi (16) and A=96 \pi +32 \pi which is A=128 \pi and when you multiply in 3.14 you get that A = 401.92 or B above.
