Odpowiedź:
h² + 8² = 10²
h² = 100 - 64 = 36
h = [tex]\sqrt{36} = 6[/tex]
Pole Δ
P = 0,5*16*6 = 48 j²
----------------------------
Korzystamy z wzoru
P = [tex]\frac{a*b*c}{4 R} / * 4 R[/tex]
4 P*R = a*b*c
R = [tex]\frac{a*b*c}{4*P} = \frac{16*10*10}{4*48} = \frac{100}{12} = \frac{25}{3} = 8 \frac{1}{3}[/tex] - pr. okręgu opisanego
================================
P = p*r gdzie p = ( a + b + c ) : 2
p = ( 16 + 10 + 10 ): 2 = 18
więc
r = P : p = 48 : 18 = [tex]\frac{8}{3} =[/tex] 2 [tex]\frac{2}{3}[/tex] - p. o. wpisanego
