Step-by-step explanation:
We are given: 
So, the integral will be used to calculate the volume.

50%
You have half of 6 so the percentage would be half of 100
To remove the parentheses, you just distribute.
So, it will become 3ax + 3b^2 - 3c +2. I don't think there is any like term in this expression.

Here's the solution ~
As we know, we can calculate the circumference of a circle in terms of its diameter as :

where, c = circumference and d = diameter
And also, circumference of circle is terms of radius (r) is :
