Answer:
The heat from the sun or heat released from the filament of a light bulb is the example of radiation.
Answer:
13. 23 boat rides; 22 are full, and the first one has 301 passengers.
12. $11,067.50
1 nanometer = 1 * 10^9 meters
so 1 nanometer = 1 * 10^7 centimeters
375 nanometers = 3,75 * 10^5 centimeters
To get the surface area of the sphere, we need to know the radius. Since the volume is given, we can get the radius.
Volume =

π r³
5000πm³ =

π r³
5000m³ =

r³
5000m³ x 3 = 4r³

=

<span>
</span>∛3750 = ∛r³
r = 15.536m
r = 15.54m
Since the radius is now known, substitute it directly to the surface area formula
A = 4π x r²
A = 4π x (15.54)²
A= 3,034.67 m² or 3,035 m²
Using the given formula, replace sa with the given surface areas and solve for s:
Surface area = 1200
s = √1200/6
s = √200
s = 14.142
Surface area = 768
s = √768/6
s = √128
s = 11.313
Difference:
14.142 - 11.313 = 2.829 inches
Round answer as needed.
