Question

A student is trying to calculate the density of an ice cream cone. She already knows the mass, but she needs to determine the volume as well. Which of the following formulas can be used to calculate the volume of the cone?

Answer 1

V= 1/3 π r²h 
this is the formula for a cone hope this helps :) 

Answer 2

Answer:

$V = \frac{1}{3}\pi R^2 H$

Explanation:

Volume of any type of cone is given as

$V = \frac{1}{3}$ (base area) (height)

Now we know that base of the triangular cone is always like a circle of radius R

Now the area of the base is given as

$A = \pi R^2$

Now in order to find volume let say the height of the cone is H

so volume of the cone is given as

$V = \frac{1}{3}\pi R^2 H$
