The surface of a hemisphere is 1/2 the surface of the entire sphere (“hemi” means 1/2), plus the area of the exposed circle (the cross section). Both parts have the same radius, R. Look up the formulas for the surface area of a sphere with radius R, and of a circle with radius R. Then do the math. read more
