Surface area including the underneath of the hemisphere = pi*radius2 + 2*pi*radius2
Total surface area = 27pi square units
Surface area of a sphere = 4*pi*radius2 Area = 49*pi square units
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.
The formula for surface area of a cylinder is: 2(pi)r2+2(pi)rh. r= radius h= height.
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 is 188.5 units2
The surface area of a sphere is 4 π r2. Since a hemisphere is half of a sphere, the equation will be 2 π r2.
Assuming that radious refers to radius, the volume is 19792 cunic units.
Surface area of a sphere = 4*pi*radius2 Area = 49*pi square units
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
Total SA = 2,199.1 units2

The formula for surface area of a cylinder is: 2(pi)r2+2(pi)rh. r= radius h= height.
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 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
