Answer:
The capacity of the cone is 70.26 cubic cm.
The surface area of cone is 109.96 square cm.
Step-by-step explanation:
We have been given that the base radius of an ice-cream cone is 3.5 cm and the slant height is 6.5 cm.
The capacity of the ice cream cone will be equal to volume of cone.
First of all, we will find height of our given cone using Pythagoras theorem.
, where,
h = Height of cone,
l = Slant height of cone,
r = Radius of cone.
Upon substituting our given values in volume formula we will get,
Therefore, the capacity of the cone is 70.26 cubic cm.
Upon substituting our given values in surface area formula we will get,
Therefore, the surface area of cone is 109.96 square cm.
