what do you call a seven sided shape?

line = 1 side\nparallel lines = 2 sides\ntriangle = 3 sides\nsquare/ rectangle = 4 sides\npentagon = 5 sides\nhexagon = 6 sides\nheptagon = 7 sides\noctagon = 8 sides\nnonagon = 9 sides\ndecagon = 10 sides\n\ni hope i have helped you.... good luck

It is not exactly round, just looks that way.\n\nSee webpage below for the correct shape.

Spheroid, ovoid, globate, globular.  The most commonly used word would be egg-shaped, but I know what you mean-an egg isnt really oval, unless you are speaking about an ant egg.  I have seen ovoid used for this kind of shape more often than any other (besides "egg-shaped").\n\n*edit* an ellipsoid can also be a perfect sphere, depending on the axes.  The perfect description for a three-dimensional oval is a *prolate spheroid*, but I have never in my life heard the term until I went searching for the answer to this question.  If you follow the Wikipedia link on ellispoid to the bottom, you see that it descibes a wide range of 3D shapes, including spheres- The link to prolate spheroid shows a shape limited only to perfect 3D ovals.\n\nhttp://en.wikipedia.org/wiki/Spheroid

a regular polygon has the same angles and sides while a irregular one has different sides and angles.

An eleven sided polygon is called a hendecagon or also an undecagon.\n\nHendecagon is derived from the Greek word hendeca meaning eleven.

fancy description of a rectangle.\n\nIf it had four congruent sides, it would be a square.

Infinite is the correct answer. Just imagine a triangle. It has three sides. Add another and you have a rectangle. One more for a pentagon. keep going until you have an infinite number of sides and viola... a circle.

I would use the trapezoid rule myself. For seven vertices:\nV0 = (x(0),y(0))\nV1 = (x(1),y(1))\nV2 = (x(2),y(2))\n...\nV6 = (x(6),y(6))\n\nFor notational convenience, define V7 = V0.\nThat is, x(7) = x(0) and y(7) = y(0).\n\nThen the area is:\n\n 6\nSUM ( x(i+1)*y(1) - x(i)*(y(i+1) ) / 2\ni=0\n\n= ( x(1)*y(0) - x(0)*y(1)\n + x(2)*y(1) - x(1)*y(2)\n + x(3)*y(2) - x(2)*y(3)\n + x(4)*y(3) - x(3)*y(4)\n + x(5)*y(4) - x(4)*y(5)\n + x(6)*y(5) - x(5)*y(6)\n + x(0)*y(6) - x(6)*y(0) ) / 2\n\n\nIf the heptagon is regular, you don't need to know the coordinates of the vertices, just the length of the regular side(s):\n\nA = (7/4) * s^2 * cot(π/7)

A cube is like a dice/ it has 6 sides. Also part of the definition of a cube is each side is a square. So it is also 6 squares. Each square is 7 x7 or 7 "squared" so each of the 6 sides is 49cm squared. cm x cm is cm squared, just like 7 x 7 is 7 squared. Don't forget there are 6 of those, multiply 49 by 6 for your total answer in cm squared.

(1) Straight-sided shapes are called polygons \n\n(2) Others are classified according to the number of sides they have.\na) triangles ( three sides) \nb) quadrilaterals ( four sides) \nc) pentagons (five sides)\nd) hexagons (six sides),\ne) octagons (eight sides)
