Hershey kisses are almost a cone shape with a height of 2.1 cm and a diameter of 3 cm. How much chocolate is in a kiss?

Given:

Height of cone shaped Hershey kisses = 2.1 cm

Diameter of the cone = 3 cm

To find:

How much chocolate is in a kiss?

Solution:

In the given problem, we need to find volume of the given cone shaped Hershey kisses.

Radius is half of the diameter and diameter of the cone is 3 cm. So, the radius of the cone is 1.5 cm.

The volume of a cone is:

Where, r is the radius and h is the height of the cone.

Putting in the above formula, we get

Therefore, there is 4.95 cubic cm chocolate is in a kiss.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
