Answer:
100π or about 314.16
Step-by-step explanation:
The formula for the area of a circle is (pi)*(radius^2)=area.
The radius is 10, so plugging that in you get pi*10^2=area.
Simplifying, you get Area=100π, or about 314.16

Answer:
48,000
Step-by-step explanation:
3,000 x 2 = 6000 (decade one)
6000 x 2 = 12000 (decade two)
12000 x 2 = 24000 (decade three)
24000 x 2 = 48000 (decade four)
Answer: 3.751*10^18kg
Step-by-step explanation:
δ =619.09−0.000097p....equa1 where p (the distance from the center of the earth) is measured in meters and δ is measured in kilograms per cubic meter.
Calculating the density of air at 5km above earth surface
P = 5000m + 6370000m = 6.375*10^6m
δ = 619.09 -(.000097* 6.375*10^6)
δ = 0.715kg/m^3 = density
Since Mass = density*volume...equ2
To calculate volume of air around the spherical earth at height 5km
V = (4/3 pai R^3) - (4/3pai r^3) ...equation 3 where R =6.375*10^6m, r = 6.37*10^6
Substituting R and r in equation 2 to solve for volume of air
V = 1.085*10^21 - 1.08*10^21
V = 5.25*10^18m^3
Substituting δ and V into equation 2 to solve for mass of air
M = 0.715 * (5.25*10^18)
M = 3.751*10^18kg
