Question:
The line segment joining the origin to the point (h, r) is revolved about the x-axis to generate a cone of height h and base radius r. Find the cone’s surface area with the parametric equations x = ht, y = rt, 0 ≤ t ≤ 1. Check your result with the geometry formula: Area = πr(slant height).
