Surface area of half a sphere = 2*pi*radius2 Surface area = 200*pi = 628.3185307 square units.

The surface area of a sphere is 4(3.14)R2where R is the radius of the sphere so the surface area of your dome is half of that. 2(314)R2
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.
1356.48 sq mt Another answer in square feet is : The formula for the surface area of a sphere is 4 x pi x radius squared. The radius is half the diameter, or 3 feet. The radius squared is therefore 9 square feet. The surface area is then 4x3.1415x9 square feet or 113.09 square feet.

If the radius of the hemispheres is 4, then that leave 4 units for the length if the straight part of the cylinder. Total surface area = surface area of 1/2 sphere of radius 4 + lateral surface area of cylinder of radius 4 and height 4 + surface area of 1/2 sphere of radius 4. = surface area of sphere of radius 4 + lateral surface area of cylinder of radius 4 = 4*3*pi*43 + pi*42*4 = 469.1 cubic units.

Total surface area = (2*pi*r2)+(pi*r2) Area = 300*pi in square units
Assuming that shere = sphere and raduis = radius, the answer is 942 square units.
there would be no" lateral" surface to a sphere because it is round , only with a cube ,pyramid or rectangular object would you have lateral surface,although it is still possible to determine the surface area and volume of a sphere, the formula to calculate the area of a sphere is 4x pie x radius squared, to calculate the volume the formula is 4x pie x radius cubed divided by 3, to calculate a hemisphere you would divide the answer in half.
A radius of a sphere is the distance from its centre to its surface. It is also half of the diameter. If you know the circumference of a circle, you can calculate its radius. Circumference divided by Pi divided by 2 = radius.
A grape is closest to a sphere. 4*pi*r*r is the surface area. Measure the grape from side to side the take half of that for the radius. The closer the grape is to a sphere the more accurate it is. The more it is to an ovoid the less it will be accurate.
The radius is 32 because the height of the hemisphere (which is half of a sphere) is the same thing as the radius (which is half the length of the diameter); the radius is the distance from the center to any point on the edge or surface of the circle/sphere.
