How do you find the surface area of a sphere to the nearest square meter?
-- You have to ask somebody for the radius of the sphere, in meters. If they tell you the diameter instead, then the radius is 1/2 of the diameter, in meters. -- Multiply (4) times (pi) times (the radius)2 . That's the surface area of the sphere, in square meters. -- Round the answer to the nearest square meter.
How do you find the area of a square and round t the nearest tenth?
bh=a or s2=a multiply two sides square one side round ex one side=3.128 3.128X3.128=9.784384 3.1282= 9.784384 round that to 9.8

Flatten it out then measure it with a ruler! ;)
Why are man hole covers round?
Round manhole covers are generally used over square manholes because they cannot fall through the manhole openings. There is a chance that if square manhole covers are used they can be turned at an angle and fall through the manhole opening. Round manhole covers can be moved more easily as well.
How do you spell manhole covers?
"Manhole covers" are simply spelled "manhole covers". The reason most of them are perfectly round is that a round cover cannot slip down into a hole that is even just slightly smaller than the cover (as can oblongs or squares).
Why is it better for manhole covers to be round rather than square?
The reason that manhole covers are round, and not square, is because a square cover could, when placed at the right angle, fall through the square hole in the ground. A circle, however, is the same diameter no matter where you measure it, and it cannot fir through a hole the same size and shape, no matter how hard anyone tried.
Why is it better to have a round Manhole cover than a square one?
A round manhole cover will not fall through the hole, A square one will.
Why is it eaisier for manhole covers to be round?
1) That way, they can easily be moved, by rolling them. 2) They can't accidentally fall into the manhole.
Why are manholes covered round?
Manhole covers are round because that is the only shape that will not fall in on itself. Having a round cover with a lip, there is no way the cover can fall or be forced into the hole it covers.
Why does the the manhole cover created round?
A square one would fall through itself but with a round one this is impossible
Why are manhole covers circular?
Microsoft and Burger King came to the conclusion that the covers are round after a year long study. At the end of this study they concluded that, logically, man hole covers must be round, otherwise the fat people that use their products would fall in, and thus would cause their profits to drop considerabliy.
Why are the manhole covers round?
Man hole covers are round so that the cover cant fall into the hole no matter what angle it is oriented at as the diameter is equal around the entirety of the circle. This would also work for an equilateral triangle but it would make it less comfortable when climbing in.
Why manhole covers are generaly round?
A circular cover is the only shape that can fit the hole no matter which way you drop it, but can't possibly fall through the hole no matter which way you drop it.
Why do you think manhole shapes like circle?
because for any person to get inside a manhole, you would think it was shaped like a round circle.
Why round shape of wheel has made instead of square?
A round wheel will roll; a square won't, or not without a great deal of effort. It's easier to move a round object than a square one.
