Answer 1

13 

a) Pir2 (do kw) = 4*4*3,14= 50,24

Pir2 = 8*8*3,14 = 200,96

200,96 - 50,24 = 150,72

b) Pir2 = 1*1*3,14 = 3,14

Pir2 = 4*4*3,14 = 50,24

50,24 - 3,14 = 47,1

c)  Pir2 = 6*6*3,14 = 113,04 

Pir2 = 10*10*3,14 = 314

314 - 113,04 = 200,96

d) Pir2 = 1*1*3,14 = 3,14

Pir2 = 6*6*3,14 = 113,04

113,04 - 3,14 = 109,9
