What is the question ?
I can think of three possibilities:
#1). What is the name of this shape ? . . . . . Heptagon.
#2). What is the perimeter of this heptagon ? . . . . . 94 cm
#3). What is the area of this heptagon ? . . . . . Very tough. You'd have to
draw it on graph paper and count up all the little boxes.
yes from 12-15cm
0.13m is equal to 13cm. So between the 12cm and the 14cm segments :)
Well, assuming it doesn't have any other sides, it's a scalene triangle.
It depends on how youre measuring him in his centaur form he is roughly 15cm tall and 13cm long
Let x be the length of one of the congruent sides, then the three sides are x, x, 3x. Perimeter = x + x + 3x = 5x = 75cm => x = 15cm Thus the three sides are 15cm, 15cm, 45cm.
We don't know whether the 15cm happens to be the hypotenuse (longest side) of the right triangle. It makes a big difference. -- If the 15cm is the longest side, then the third side is 7.483 cm. (rounded) -- If the 13cm and the 15cm are the "legs", then the hypotenuse is 19.849 cm. (rounded)
Perimeter is the total of all the sides. Let's assume your part-question relates to a rectangle. Four sides: 2 x 8cm and 2 x 15cm. I'm sure you can work it out from there...
Perimeter = 8*15 = 120 cm
sqrt(15) = 3.873 cm (approx)
Using Pythagoras' theorem: 15 times the square root of 2 cm in length
Basically, the perimeter of a shape is the total legnth of all it's sides, therefore to write an expression for it, you need to get the legnths of the sides (even if there is a letter (eg: n)), then put them into an expression. For instance: A polygon has 2 sides that are 15cm long, 1 side that is 22cm long, 4 sides that are n long and 3 sides that are a long. To write the expression for the perimeter of this polygon as basically as possible, you would write: 15cm + 15cm + 22cm + n + n + n + n + a + a + a Now you need to simplify it: 52cm + 4n + 3a If you were asked this question, you would write 52cm + 4n + 3a as your answer. That is an expression for the perimeter of that particular polygon. If you apply the same theory to any question like the one you asked about, you would get it right.
A regular polygon is a polygon in which all the angles and sides are equal, say on a regular polygon if one side is 15cm if you know that they are all equal, all the other sides are 15cm, also you can assume on a regular polygon, that if one angle is 75o all the other angles are 75o
If you are talking about such a small tank that the fish is touching all sides at the same time, then yes. But if you are talking about a little goldfish in a 15cm x 15cm tank then no, it will just be a bit uncomfortable.
If 15cm is the diameter then the radius is 7.5cm If the circumference is 15cm then the radius is 7.5/pi cm
15cm = 5.9 inches.
15cm-58mm equals = -43
90cm (six sides x 15 = 6 x 15 = 90)
15cm equates to about six (5.90551) inches.
15*15 = 225 square centimetres.
The circumference of a circle with diameter of 15cm is about 47.12cm
The circumference of a circle, if the diameter is 15cm, is about 47.12cm
