picture a sphere. the surface area of a sphere is 4*pi*r^2.
now, cut it in half. the surface area is 4*pi*r^2 / 2 =2*pi*r^2
this is without including the bottom circular base
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
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.
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.
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 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
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.
Total surface area = 1847.26 sq cm.
total curved surface area = 2*pie*r^2
