Question

please answer please ​

Answer 1

Answer:

11. Number of faces = 9

Number of edges = 16

Number of vertices = 9

F + V= 9+9 = 18

E + 2 = 16+2 = 18

F + V= E + 2 = 18

Hence, Euler's formula is verified

Step-by-step explanation:

12. 300,000,000 in standard form = It is correct as it is in the standard form

Answer 2

Step-by-step explanation:

no. of face - 9

no of edges - 18

no of vertical- 18

so-

F+ V =9+9 =18

E + 2= 16+2=18

F + V= E+2=18

euler's formula is Verified

hope it helps you
