Calculating Volume and Antiderivatives

The video tutorial explains how to evaluate a definite integral to find the volume of a geometric shape. It begins with setting up the integral, expands the expression, calculates the antiderivative, evaluates the integral at specific limits, and concludes with simplifying the final result. The process involves expanding expressions, using antiderivatives, and performing arithmetic operations to reach the solution.
