Hemispherical hollow

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

Correct answer:

V =  3.351 l

Step-by-step explanation:

v=10 cm dm=10:10  dm=1 dm D=28 cm dm=28:10  dm=2.8 dm  r=D/2=514/2=5 214=1014=57=1.4 dm r1=r2(rv)2=1.42(1.41)21.3416 dm  1 l = 1dm3 V=61 π v (3 r12+v2)=61 3.1416 1 (3 1.34162+12)=3.351 l
