I need help with this questions. Please explain thoroughly and Please write clear, readable answers. Thank you so much!

The base of a solid is the region between one arch of the curve y = sin(x) and the x-axis, and cross- sections ("slices") of the solid perpendicular to the base (and to the x-axis) are squares. Represent the volume of this solid as a definite integral, then evaluate the integral.

The graph of the function is a straight line. Calculate the length of line segment.

y = 3 + 2x for 0 x 2

(a) using the distance formula between 2 points and

(b) by setting up and evaluating the arc length integrals.
