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 answer is the western hemisphere.
Canada is the country with the largest area in the Western Hemisphere.
The Southern Hemisphere!
Canada has the largest land area in the western hemisphere
I think but pretty sure but the southern hemisphere because of the massive area of Europe
The Southern hemisphere has more water than the Northern hemisphere.
The hemisphere north of the equator is called the Northern Hemisphere.
Shaded area(in the northern hemisphere). In the Southern hemisphere the north side is the sunny side or sunny area.
what country has the largest land area in the western hemisphere
The Southern Hemisphere has more area of water then the Northern Hemisphere.
It is called solstice. It is summer solstice in the hemisphere where the area is at its maximum, and winder solstice in the other.
