Answer: 8π square meters

Explanation:

First, we convert the angle of the sector to radians, which is 30 degrees.

Note that 180 degrees is equal to π radians. Since 30 degrees is equal to 180 degrees divided by 6,

30 degrees = π/6 radians

Thus, the angle of the sector in radians is π/6.

So, the area of the sector is given by

(Area of sector) = (1/2)(radius)²(angle of the sector in radians)
= (1/2)(radius)²(π/6)
= (π/12)(radius)²
= (1/12)(π)(radius)²

Note that

(Area of the circle) = (π)(radius)² = 96π

Therefore, the area of the 30-degree sector is given by

(Area of the sector) = (1/12)(π)(radius)²
= (1/12)(Area of the circle)
= (1/12)(96π)
(Area of the sector) = 8π square meters
