21 chickens and 23 goats=44
21x2=42 23x4=92
42+92 = 134 legs
x=goats y= chikens goats 4 legs chickens 2 legs
x+y=44 x=44-y
4(44-y) + 2(y) =134
176-4y +2y = 134
176-2y=134
-2y= -42
-y= -21
y=21

Answer:
591.1

h= Hight = 8
r= radius = 8.4
Answer:
A = 145cm
Step-by-step explanation:
A+B+C = 445cm
b = 1/2c
a = b+45 = 1/2c + 45
445 = c + (0.5c) + (0.5c + 45)
445 = 2c + 45
445 - 45 = 2c
400/2 = c
c = 200cm
a = 1/2c + 45 = 1/2*200 + 45 = 100 + 45 = 145cm
