I am trying to find the estimated volume of a rotational solid that is a cone. It is an estimate because I am cutting the cone into 8 cylinders, and finding the volume of each. Each cylinder is 1/2 inch tall, and their radi are as followed, 3/32, 3/8, 5/8, 7/8, 9/8, 11/8, 13/8, 15/8, and 17/8.
How would I go about setting this up so that the answer is 23.77?
I thought it was V = π r ^2(.5) ... But I'm not getting the answer 23.77. ):
Also, what is the value of each variable/reason for it being present in the equation?
Hopefully that made sense. lol
I'd really appreciate any help I can get. Thank you soooo much!~ <3
