When finding the volume of this shape, there would practically be a formula that we would have to use, in order to solve this on how we are suppose to do.
We know that the radius would then be 4, and therefore, we would just plug this in into the formula which would be illustrated below.
All we would have to do, is to plug the number 4 into the proper location in the formula.
In a decimal form, your correct answer would then be 268.08.
By as we can see above, we would have to convert the decimal form, into a fraction form, and this would be shown below.
Your correct answer should be
(option a)
