∙ 14y ago
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.

What is the Surface area of an oval table?
the formula for calculating the surface area of an oval is A = Pi * a * b where a & b are the semimajor(half the long) and semiminor(half the short) axes
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.
Formula for calculating the area of sphere?
The formula for calculating the surface area of a sphere is 4πr², where r is the radius of the sphere. This formula represents the area covered by the curved surface of the sphere.
What is the formula for calculating area of a hemisphere?
1/2*pi*r2
What is formula for area of semi sphere?
Formula for calculating the area of a hemisphere... Area = (4 x pi x r2) / 2
Formula for calculating surface area of a cone?
The answer will depend on what information you have.
How do you find the surface area of a hemisphere?
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.
What is the formula for calculating surface area of dished end?
area of dish end
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 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

What is the formula for calculating surface area of hemispherical dished end?
The area of a sphere is 4 (pi) (radius)2. The area of 1/2 of the sphere is 2 (pi) (radius)2. If you want to add in the flat end of the hemisphere, that makes the total surface area 3 (pi) (radius)2.
