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.

A = 2 x pi x r (r + h)
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.
