Question 61755
I am only able to answer two of your questions:


1.) To find the volume of a sphere you use this formula:


[4/3] X [Pi] X [radius]^3 and is expressed in cubic units

[4/3] X [3.14] X [2 cm]^3 = [4/3] X [3.14] X [8]= 34.49 cubic centimeters.


2.) To find the volume of a cone you use this formula:

The volume of a cone is [1/3][PI][radius]^2[height]and is expressed in cubic units. Since you gave the full width the radius would be 2 cm.
[1/3][3.14][2cm]^2[5cm]= [1/3][3.14][4cm][5cm]= 20.93 cubic centimeters
