πr² = 16 π / : π
r² = 16
r = 4 cm
b) 10 cm²
πr²=10/ : π
r= √10/π cm (to pod jeden pierwiastek)
c) 400 m²
πr²=400/ : π
r² = 400/π
r=20/√π
w moich obliczeniach litera V znaczy symbol pierwiastka!!!!!!!!!!!!!!!!!!!!!!!!!!!
p=πr²
a).16π=πr² I :π
16=r²
r=4cm
b). 10=πr² I: π
10:π=r²
r²=10:π
r= V(10:π) cm
c) 400=πr² I:π
400:π=r²
r= V 400 : Vπ
r= 20 : Vπ
dasz mi najlpszy?? ^^

Chyba tak :)
