If we join the Center with different corners of the polygon,we find 10 Isoceles triangle with equal side=9.14cm, Making an angle of 36° between the equal sides.
Area of 1 triangle= a*b*sinC/2
= 9.14*9.14*Sin36°/2
= 9.14*9.14*0.587/2
=24.51 cm^2
Area of 10 triangle= 24.51*10
= 245.1cm^2
Answer:
Arithmetic sequence
for 
Step-by-step explanation:
We are given that a sequence
We have to identify the sequence as arithmetic or geometric and write an explicit formula .
When the difference of consecutive terms is constant then the sequence is an arithmetic.
Hence, the sequence is an arithmetic.
for
The Pythagorean equation relates the sides of a right triangle in a simple way, so that if the lengths of any two sides are known the length of the third side can be found. Another corollary of the theorem is that in any right triangle, the hypotenuse is greater than any one of the other sides, but less than their sum.

11/15-2/5
Multiply 2 and 5 to get a common denominator of 15
11/15-6/15
=4/15
