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.
The curved surface area is 89.76527 units2 and the total surface area is 134.6479 units2
Surface Area = ~6,870.7 ft2
The surface area of a semicircle has the round surface which is half a sphere and also has the flat surface which is a circle.
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
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.
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.
The answer for the hemisphere is half the volume of a sphere, which is given by the formula (2/3)πr³, where r is the radius. The surface area of a hemisphere is half the surface area of a sphere, given by the formula 2πr².
The curved surface area is 89.76527 units2 and the total surface area is 134.6479 units2
Surface Area = ~285.1 ft2
Surface Area = ~6,870.7 ft2
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 surface area of a semicircle has the round surface which is half a sphere and also has the flat surface which is a circle.
Volume = 2/3πr3 Surface area = 3πr2
Total surface area = 1847.26 sq cm.
