Slant height of the conical tent:
To find the slant height of the conical tent, we can use the Pythagorean theorem. The slant height is the hypotenuse of a right triangle formed by the height and the radius of the base of the cone.

Using the given information:
Vertical height of the tent (h) = 3 m
Diameter of the tent (d) = 8 m

We can find the radius (r) by dividing the diameter by 2:
r = d/2 = 8/2 = 4 m

Now, we can use the Pythagorean theorem to find the slant height (l):
l² = r² + h²
l² = 4² + 3²
l² = 16 + 9
l² = 25
l = √25
l = 5 m

Therefore, the slant height of the conical tent is 5 m.

Area of the tarpaulin used:
To find the area of the tarpaulin used, we need to find the lateral surface area of the cone. The lateral surface area of a cone can be calculated using the formula:

Lateral surface area = πr * l, where r is the radius and l is the slant height.

Using the given information:
Radius (r) = 4 m
Slant height (l) = 5 m

Lateral surface area = π * 4 * 5 = 20π ≈ 62.83 m²

Therefore, the area of the tarpaulin used is approximately 62.83 square meters.

Length of the tarpaulin used:
To find the length of the tarpaulin used, we need to calculate the circumference of the base of the cone. The circumference of a circle can be calculated using the formula:

Circumference = πd, where d is the diameter.

Using the given information:
Diameter (d) = 8 m

Circumference = π * 8 = 8π ≈ 25.13 m

Since the width of the tarpaulin is given as 2.5 m, we can calculate the length of the tarpaulin used by multiplying the circumference by the width:

Length of tarpaulin used = Circumference * Width = 25.13 * 2.5 = 62.825 m

Therefore, the length of the tarpaulin used is approximately 62.825 meters.

In conclusion, the slant height of the conical tent is 5 m, the area of the tarpaulin used is approximately 62.83 square meters, and the length of the tarpaulin used is approximately 62.825 meters.
