The lateral surface area, that is, the part curved in 3-dimensional space, is equal to the perimeter of one circular base multiplied by the height. The perimeter of a circle with radius 10 is 20(pi); therefore, the lateral area is 20(pi)16 = 6.0 X 102 to the justified number of significant digits.
Lengths of: equal side+equal side+base = perimeter
The perimeter is equal to Pi times the diameter.
The perimeter of a quadrilateral is always equal to the sum the lengths of its four sides. So perimeter = Side1 +Side2 + Side3 +Side4. If the quadrilateral happens to be a parallelogram, a quick way to calculate the perimeter is 2 x length of base + 2 x length of height.
It will have 3 equal sides of 20cm Using Pythagoras's' theorem its height is 17.32050808cm Using the formula for area:1/2*base*height its area is 173.32050808cm2
Assuming the shape is a regular dodecagon, the formula for calculating the perimeter for a dodecagon of side length n is equal to 12n.

Well, the lateral edges are equal to the height. Use the pathogorean theorem using a^2+b^2=c^2.
If you know only the base and height, you have two unknown sides and it is not possible to calculate the perimeter. The perimeter can have any value greater than or equal to 5+sqrt(89) cm.
The area A is equal to 2πrh, where r is the radius and h is the height.
The sum of the interior angles of any triangle always equals 180 degrees. With equal length sides, each angle will always be 60 degrees, irrespective of the length of the sides. Additionally, 1/2 B (base) x H (height) = A (area). If a line is drawn bisecting any interior angle to the nearest point on the opposite side (lateral), two right triangles will be produced. AND interestingly, when the two right triangles are placed next to each other along their hypotenuse, a rectangle is formed. Thus the formula for area of an equal lateral triangle can be shown to be the same as the formula for a rectangle when the length & width of the sides of the rectangle equal 1/2 the base and the height of the equal lateral triangle...QED
volume is equal to length x breadth x height
