round
-- 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.
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

A square centimeter is an area ... a definite amount of the surface of a tabletop,a wall, a piece of paper, a floor, a board, a cloth, a ball, etc.It can be long and skinny, round, oval, triangular, or have a wiggly and irregular outlinelike a blob. But the total amount of surface that it covers is always the same amountas a square with sides that are 1 centimeter long. No matter what shape it is, it takesthe same amount of paint or glue to cover it.
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.
Round manhole covers are preferred over square ones because they cannot fall into the hole they are covering regardless of their orientation, making them safer for workers and pedestrians. Additionally, round covers are easier to move since they can be rolled, while square covers need to be lifted and aligned to be placed back.
"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).
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.
Manhole covers are easier to handle and align when they are round because a circular shape cannot fall into the hole it covers, reducing the risk of accidents. Round covers are also easier to roll into place and do not need to be rotated to fit properly. This makes them more practical and efficient for workers who need to access the manhole.
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.
A square one would fall through itself but with a round one this is impossible
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.
Manhole covers are round because a round shape cannot fall through its own opening, unlike squares or other shapes which can if they are rotated. This design ensures safety for workers and the public, as well as making it easier to seal the cover against unauthorized entry.
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.
because for any person to get inside a manhole, you would think it was shaped like a round circle.
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.
