The answer is:
The total area is:
To find the cloasest value to the total surface area that will be painted, we need to calculate the area of a single sphere, and then, multiply it by 5.
We know that the diameter of each sphere is 7 centimeters, so, calculating we have:
Calculating the radius we have,
Then, calculating the area, we have:
Now that we have calculated the surface area of a single sphere, we need to calculate the area of the five spheres.
So, calculating we have:
Hence, the total area is:
Have a nice day!
Volume = 4/3 pi r^3 = 4/3 pi 343/8pi^3 = 343/6pi^2
there are 5 spheres so total is 5*343/6pi^2 which is approximately
Atmosphere, Cryosphere, Hyrdrosphere, Biosphere, and Geosphere
B) Interactive with one another
Humans (biosphere) built a dam out of rock materials (lithosphere).
•Water in the lake (hydrosphere) seeps into the cliff walls behind the
dam, becoming groundwater (lithosphere), or evaporating
into the air (atmosphere).
•Humans (biosphere) harness energy from the water (hydrosphere) by
having it spin turbines (lithosphere) to produce electricity.
The marine environment involves the interaction between the lithosphere, the hydrosphere, and biosphere. The organism in the oceans feeds on the nutrient in the oceans to build their own biomass. This organism when they die, sink to the ocean floor and settle as sediments. Over time, these sediment compact to become sedimentary rocks that are part of the lithosphere.
Lithosphere, Hydrosphere, Biosphere, Atmosphere. I will now list an example of each in the same order. Rocks of Earth, Water, all living organisms(plants, etc.), and gasses surrounding the earth. I am not sure if this is a trick question, because the main ones (or amount) just make up 4, but there is probably some kind of subset that you could use. Hope this helped!
The five spheres are
Explanation: Because this is true
The stratosphere, which hot air balloons can reach
The mesosphere, where rain comes from
The thermosphere, home to the northern lights
The exosphere, where rockets and satellites can be found
