volume of a cone=(1/3)(pi)r²h.
total volume of ice cream=volume of cone + volume of hemisphere
∴volume of cone=(1/3)(22/7)(3.5)²(12.5)
=(22/21)(12.25)(12.5)
=(22/21000)(1225 x 125)
=(11 x 245 x 5)/84
=13475/84.
volume of hemisphere=2/3 x (pi) x r
=2/3 x 22/7 x 3.5
=44/6
∴volume of ice cream =14091/84 cm³.
hope it helps. pls mark as best answer.
