Answer:
1) Volume = ⅓×pi×r²×h
= ⅓×3.14×7²×14
= 718.01 in³
2) ⅓×3.14×5²×10
= 261.67 cm³
3) r = 12÷2 = 6
Volume = (4/3)×3.14×6³
= 904.32 mi³
4) 3.142×4²×5
= 251.2 ft³
5) radius = 2
(4/3)×3.14×2³ = 33.49 ft³
6) radius = 2
3.142×2²×3 = 37.68 m³
Answer:

Step-by-step explanation:
Answer:
77
Step-by-step explanation:
just do 500-423
X= 6
Y= 0
Z= -2
CHECK
3x + y -2z =22
3(6) + 0 -2(-2) =22
18 + 0 +4= 22
22=22
x+5y+z =4
6 +5(0)+ -2 =4
6 + 0 +-2 = 4
4=4
x+3z=0
6 + 3(-2) =0
6 -6 = 0
0=0
