The circular sector's area, computed using the formula with the angle in radians, is 25π/6 square inches which is approximately 6.54 in².
To determine the area of a circular sector, we use the formula A = (1/2) r^2 θ, where r is the radius and θ is the central angle in radians. In this case, with a radius of 5 inches and θ = 30 degrees, it's important to convert degrees to radians.
The conversion involves multiplying the degree measure by π/180. For 30 degrees, this results in π/6 radians. Substituting this into the formula, we get:
A = (1/2) × (5)^2 × (π/6)
Solving this expression yields the area of the circular sector:
A = 25π/6
A ≈ 6.54 in²
Hence, the area of the circular sector with a 5-inch radius and a central angle of 30° is 6.54 square inches
In summary, applying the area formula with proper conversion of the angle to radians results in an area of 6.54 square inches for the given circular sector.
