To find the curved surface area of the conical tent:

- Formula: Curved surface area of a cone = ??rl, where r is the radius, and l is the slant height.

- Given: Height (h) = 10 m, Diameter of base = 48 m.

- Radius: r = Diameter/2 = 48/2 = 24 m.

- Slant height (l): Use the Pythagorean theorem, $l = \sqrt{r^{2} + h^{2}} = \sqrt{24^{2} + 10^{2}} = \sqrt{576 + 100} = \sqrt{676} = 26$ m.

- Curved Surface Area: ??rl = ?? × 24 × 26 = 624?? m².

- Option 1: 576?? - Incorrect calculation.

- Option 2: 1248?? - Greater than actual value.

- Option 3: 152?? - Much less than actual value.

- Option 4: 624?? - Correct ??
