Answer:
still air = 815, wind = 40
Step-by-step explanation:
x+y=against
x-y=with
8(x+y)=6200
8(x-y)=6840
Divide 8.
x-y=775
x+y=855
Subtract. 2 from 1
2y=80
y=40
x=815
Hope this helps plz hit the crown :D

Explanation:
a scale drawing that has a scale of 1 centimeter to 2 feet, with a width of 6 centimeters and a length of 8 centimeters
a scale drawing that has a scale of 1 centimeter to 8 feet with a width of 1.5 centimeters and a length of 2 centimeters
Answer:
arc length = radius * angle in degrees * (PI / 180)
arc length = 6 * 160 * (PI/180)
arc length = PI * 960 / 180
arc length = PI * 5 + (60/180)
arc length = (16/3) * PI
Step-by-step explanation:

Answer:
A = 7,241.2454026112 square mm.
or exact : A = 2,304.96*π sq mm
Step-by-step explanation:
Cylinder formula: A = π* r^2 + 2 *π * r* h + π*r^2
is the surface area.
d = 2r = 39.2 mm
h = 39.2 mm
r = 19.6 mm
A = π* r^2 + 2 *π * r* h + π*r^2
A = 2* π* (19.6)^2 + 2π (19.6)*(39.2)
A = 2,413.748467537 + 4,827.496935
A = 7,241.2454026112 square mm.
or
A = 2*pi* (768.32 + 384.16)
A = 2*1,152.48* pi
A = 2,304.96*π sq mm
