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 find radius of a hemisphere?
To find the radius of a hemisphere, you can use the formula for the volume or surface area, depending on the information you have. If you know the volume ( V ) of the hemisphere, the radius ( r ) can be calculated using the formula ( r = \left(\frac{3V}{2\pi}\right)^{1/3} ). If you have the surface area ( A ), use the formula ( r = \sqrt{\frac{2A}{3\pi}} ).

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
