proszę rozwiązać zadania z matematyki wszytsko z załącznika dałam 23 pkt.
Zad. 1
Dane : Szukane :
r = 10 Pw ?
a= 90 st
B = 135 st
q= 225 st
Pw = pi*r^2 * a/360st
Pwa= pi * 10^2 * 90 st/360 st
Pwa = 100 pi * 1/4 = 25 pi
Pwb= pi*r^2 * B/360st
Pw = 100 pi * 135/360
pw = 100pi * 3/8
pwb= 75/2 Pi = 37.5 pi
Pwq= pi*r^2 * q/360st
Pwq = 100 pi * 225/360
Pwq= 100pi * 5/8
pwq= 125/2 pi = 62.5 pi

Dane: Szukane :
L=10pi r ?
a = 72 st Pw ?
L= 2pi*r
r= L/2pi
r= 10pi /2pi = 5
Pw = pi*r^2 * a/360
Pw= pi * 5^2 * 72/360
Pw = 25 pi * 1/5
Pw = 5 pi
