What is the surface area of a cylinder with end that are half sphere with a radius of 4 and height of 12?

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.


Formula for surface area of a spherical dome?

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


Why isn't the surface of a hemisphere not half the surface area of a sphere?

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.


What is the surface area of a sphere with a diameter of 6 feet?

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.


Find the total surface area of this half sphere with a radius of 10?

Total surface area = (2*pi*r2)+(pi*r2) Area = 300*pi in square units


Total surface area of half shere with a raduis of 10?

Assuming that shere = sphere and raduis = radius, the answer is 942 square units.


How do you find the lateral area of a sphere?

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.


What is the radius of a sphere?

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.


What is the surface area of a grape?

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.


What is the radius of a hemisphere dome with a height of 32?

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.
