What is the difference between curved surface area of hemisphere and total surface area of hemisphere?

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


How can we calculate the flux for hemispheres of different radii?

To calculate the flux for hemispheres of different radii, you can use the formula for flux, which is the surface integral of the vector field over the surface of the hemisphere. The flux can be calculated by taking the dot product of the vector field and the normal vector to the surface, and then integrating over the surface area of the hemisphere. The formula for flux is given by F dS, where F is the vector field, dS is the differential surface area element, and the integral is taken over the surface of the hemisphere.


How do you find the total surface area of a hemisphere whose diameter is 8 inches?

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.


How do you find the surface area of a hemisphere?

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.


How can one calculate the flux for hemispheres of varying radii?

To calculate the flux for hemispheres of varying radii, you can use the formula for flux, which is the surface integral of the vector field over the surface of the hemisphere. The flux can be calculated by taking the dot product of the vector field and the unit normal vector to the surface, and then integrating over the surface area of the hemisphere. The formula for flux is given by F dS, where F is the vector field, dS is the differential surface area element, and the integral is taken over the surface of the hemisphere.


Find the surface area of a hemisphere with a radious of 3?

Surface area including the underneath of the hemisphere = pi*radius2 + 2*pi*radius2 Total surface area = 27pi square units


What is the answer for the hemisphere?

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.


What is the formula for calculating surface area of a hemisphere?

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.


How do you compare the surface are to volume ratio of cells of different size?
