Question

How much ice cream can be put into a cone with radius 3.5 cm and height 12cm​

Answer 1

hi friend :)
Radius of cone = 3.5 cm
Height of cone = 12 cm
Voume of cone = 1/3×π×r^2×h
Vol. of ice cream that can be put in the cone
= 1/3×22/7×3.5×3.5×12 cm ^ 3
= 154 cm^3

Answer 2

153.86 cm^2 of ice cream

Explanation:

First we find the surface area which is pi*r^2

3.5^2=12.25

12.25*3.14=38.465

The volume of a cone is h/3*the surface area.

12/3=4

4*38.465=153.86
