Answer:
The circumference of the base of the cone = 2\pi r. Therefore area of the curved surface = \frac{1}{2}\times |\times 2\pi r. Area of the curved surface = πrl. Total surface area of a cone = Area of the circular base + area of the curved surface. Total surface area of a cone = \pi r^{2}+\po rl.
