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.
There are infinitely many. Calculate the square root of 250, and round it up. The square of this number will be the first one. The square of any larger integer will also be a perfect square larger than 250.
square pizza = 15 * 15 = 225 square inches round pizza = 3.1416 * 8 * 8 = 201.06 square inches So square pizza is bigger area.
1 A square pyramid has 1 at the top and 4 round the base, a total of 5. A triangular pyramid has 1 at the top and 3 round the base, a total of 4. The square pyramid has 5 - 4 = 1 extra vertex (round its base).
When your number is less than fifty.
Yes they will
Round trampolines are much better. The strain on the springs is more evenly distributed. There is more stretch and flex in a round trampoline as opposed to a square trampoline. But it doesn't really matter both are just as good.
A round manhole cover will not fall through the hole, A square one will.
Square drinking glasses better than round ones for three reasons: (1) You can get a better grip on a square glass. (2) You can drink out of the corner, if you wish. (You benefit from the "pitcher effect" and don't' have to open your mouth as wide.) (3) They are more stylish! These are my personal opinions having chosen square glasses for my home use for the past couple of years.
It is not square. It's closer to being round than 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.
You can get a square parachute to descend extremely rapidly - indeed, there have been a number incidents (sometimes involving fatalities) when skydivers 'spiralling' close to the ground have had their reserve parachutes deployed automatically by the Automatic Opening Device (sometimes call the Automatic Activation Device). Indeed, a skydiver was killed a few weeks ago in Bad Lippspringe, Germany because he turned rapidly too close to the ground. A round parachute would, depending on your weight, let you down faster than a square on 'half brakes', although some small squares (<170 sq ft) would give you a pretty heavy bump unless you flared just before landing.
The aim is to use the right material and the right shapes , i once tried making a parachute and plastic works better than cloth or newspaper or anything else.
If a tire were square, than it would be a dick.
