Volume = 2/3πr3 Surface area = 3πr2
Surface area including the underneath of the hemisphere = pi*radius2 + 2*pi*radius2 Total surface area = 27pi square units
The surface area of a whole sphere, of radius r, is 4*pi*r2.The area of the curved surface of a hemisphere is, therefore, 2*pi*r2.The area of the flat surface is that of a circle of radius r, that is = pi*r2.So the total surface area of a hemisphere is 2*pi*r2 + pi*r2 = 3*pi*r2.
Calculate the radius (it is half the diameter).Use the formula for a sphere: area = 4 x pi x radius2.Since a hemisphere is half a sphere, divide this result by 2.Question:Do you mean the surface area to include the flat face of the hemisphere?If so then follow the above instructions and add pi*42 to your answer which will give you the complete surface area of the hemisphere.
Surface Area = ~6,870.7 ft2
Curved surface area of a hemisphere means only the bent part of it , i.e,the part which looks like half of a sphere. Total surface area of a hemisphere is the circular top of a hemisphere + curved surface area of a hemisphere. So the formula goes like this: Curved surface area of hemisphere= 2πr2 Total surface area of hemisphere= 2πr2 + πr2 = 3πr2
The northern hemisphere has more land area compared to the southern hemisphere. About 68.3% of the Earth's land area is located in the northern hemisphere.
The Northern Hemisphere has more land area than the Southern Hemisphere. About 68% of the Earth's land area is located in the Northern Hemisphere.
Canada is the country with the largest area in the Western Hemisphere.
The Southern hemisphere has more water than the Northern hemisphere.
The Northern Hemisphere has more land area than the Southern Hemisphere. The majority of Earth's landmass is located north of the equator.
I think but pretty sure but the southern hemisphere because of the massive area of Europe
Canada has the largest land area in the western hemisphere
Russia has the largest land area in the eastern hemisphere.
Canada has the largest land area in the Western Hemisphere.
The hemisphere north of the equator is called the Northern Hemisphere.
To find the surface area of a hemisphere, you can use the formula: SA = 2πr^2, where r is the radius of the hemisphere. This formula takes into account the curved surface area of the hemisphere.
