Question

Proszę rozwiąż A i B ( w złączniku)

Pole powierzchni całej wynosi...

Answer 1

1)   a = 8 ,     Pc = ?                                 a²√3

        Pc = Pp + Pb,         Pc = a² + 4 · ---------  =  a² + a²√3

                                                                     4

         Pc = 8² + 8²√3 = 64 + 64√3 =64( 1 + √3) [ j² ]

2)   a = 6,      Pc = ?

        Pc = 6² + 6²√3 = 36 + 36√3 = 36( 1 + √3) [ j² ]

 

 

Answer 2

A)

a=8cm

Pc=Pp+Pb

Pp=8*8=64

Pb=√12(12-8)(12-8)(12-8)

Pb=√12*4*4*4

Pb=√768

Pb=12√3

 

Pc=64+12√3cm²

 

B)

a=6cm

Pp=6*6=36

Pb=√9(9-6)(9-6)(9-6)

Pb=√9*3*3*3

Pb=√243

Pb=9√3

Pc=36+9√3
