Hemispherical hollow

The vessel hemispherical hollow is filled with water to a height of 10 cm =. How many liters of water are inside if the inside diameter of the hollow is d = 28cm?

Correct result:

V =  3.351 l


v=10 cm dm=10/10  dm=1 dm D=28 cm dm=28/10  dm=2.8 dm  r=D/2=2.8/2=75=125=1.4 dm r1=r2(rv)2=1.42(1.41)21.3416 dm  1 l=1dm3 V=16 π v (3 r12+v2)=16 3.1416 1 (3 1.34162+12)=3.351 l
