Question

An ice cream cone is the union of a right circular cone and a hemisphere that has the same circular base as the cone.Find the volume of the ice cream,if the height of the cone is 9 cm and the radius of its base is 2.5 cm​

Answer 1

volume of ice cream=134.22cm^3

volume of ice cream=volume of cone+volume of hemisphere

=1/3πr^2+2/3πr^3

=1/3πr^2(2h+r)

=1/3×22/7×2.5×2.5(2×9+2.5)

=134.22cm^3

Answer 2

Answer:

1.(b.)1375/42 = volume of hemispherical end

2.(d) 825/14 = volume of only cone

3.(c)πrl+πr^2 T.S.A. OF CONE

4. (d.) remain unaltered
