The surface area of a sphere is 4 \pi  r^{2}.

Hence, the surface area of a hemisphere is half that, 2 \pi  r^{2}.

If the base is also included then the surface area will be 3 \pi  r^{2}.

Given,

Diameter = 26 cm

Therefore, Radius = \frac{26}{2} = 13 cm

Thus, 

Area = 3 *  \pi *  13^{2} = 3 * \pi * 169 = 507 \pi = = 1592.8 cm^{2} [approx.]
