Question

a toy is made in the form of a hemisphere surmounted with height 8cm and diameter 12 cm.Find the volume.....

Answer 1

Answer:

Step-by-step explanation

D= 12 cm

r= 6cm

h= 8cm

Vol. Of hemisphere= 2/3 π r3

Vol. Of cone = πr2h/3

Total vol. = vol. Of cone + vol. Of hemisphere

=> 2/3πr3+πr2h/3

=> π/3r2(4/3h+ 2r)

π/3 *36(68/3)

88*68/7= 854.85cm3
