# What is the square root of an octagon with 5 foot sides?

Numbers have square roots. Shapes don't.

### How do you algebraically determine the perimeterof arectangular octagon inscribed in a circle of diameter 15cmEach side of the octagon is 6.9cm from the centre of the circle?

We know that an octagon is an eight-side polygon. Since each side has the same distance form the center of the circumscribed circle of the octagon, this octagon is a regular octagon. If we draw the radii of the circle (their endpoints there are at the vertexes of the octagon), we form 8 isosceles triangle, which radius represents two their congruent sides with a measure of 7.5 cm, and the distance drawn from the center…

### What is the diagonal measure of a twelve foot square?

Two sides of the square, along with the diagonal, form a right triangle. Therefore, we apply the Pythagorean theorem: a2 + b2 = c2. a and b are the sides of the triangle that connect with the right (ninety-degree) angle, and c is the side opposite the right angle. 122 + 122 = c2 144 + 144 = c2 288 = c2 288 = c2 Take the square root of both sides of the equation…

### How do you find the perimeter of a square when only the area is given?

Since you know that a square has four congruent sides, you know that the area is s2. If you want to find the length of one side, take the square root of both sides, so you're left with s= the square root of the area. A square has 4 sides, so to find the perimeter (4s = P), multiply both sides by 4. So you end up with this: P= 4A1/2 where P is the…

### What is the formula to find the volume of an octagon?

You don't find the "volume" of a flat figure. Perhaps you want its surface area. The area for a regular octagon of side "a" is 2 (1 + root(2)) a2, where "root" is the square root function. If it is not a regular octagon, I don't think there is a simple formula to find the area - you'll have to split it up into simpler figures, for example triangles. ================================== Answer #2: Here is the…

### What do you call a parallelogram that has all sides the same length?

If all sides are equal,and there are only 4 sides,then that would make it a square.If there are 6 sides and they are all equal,then it's a hexagon,and 8 equal sides would be an octagon,etc.The names of these shapes often have root words in them that desribe the number of corners or sides.Octagon has the root prefix of -oct,which means 8,and -hex means 6, pentagon has the root prefix of -pent,which means 5.It's actually quite…

### How do you figure out the angles if the hypotonuse is 128?

In a triangle ABC, when hypotenuse is 128 unit which is right angled at A. By phythagoras theorem H square = P square + B square root of hypotenuse = ROOT of 8square + root of 8square it means other two sides are equal therefore . assuming the sides equal to x we have 2x square=128 x square= 64 x = -+8 but length is always positive. therefore other two sides = x= 8

### What is the Diagonal of a 24 by 36 foot building?

Pythagoras told us that the hypotenuse of a right triangle equals the square root of the sum of the squares of the other two sides. If you draw a line from corner to opposite corner of your building you divide the floor into two triangles with the same length sides and the hypotenuse is the diagonal of the building. So, taking one of the two triangles the length of the hypotenuse is equal to the…

### What is the perimeter of a square with an area of 49?

The area of square is the square of one of its sides, which are all equal. To find the value of a side, take the square root of the area. In this case the square root of 49cm2 is 7cm. The perimeter is the sum of all four sides of the square, so the perimeter of a square with an area of 49cm2 is 7+7+7+7 = 28, or 4x7 = 28.

### How long is each side of a 5 inch diameter octagon?

The length of a single edge of an octagon can be calculated by measuring the diameter, then dividing this length by the square root of the sum of four and two times the square root of two, which would be written in a calculator as sqrt(4+(2*sqrt(2))). In this case, a five inch diameter equates to approximately 1.913 inches per side.
