To find the area of a sector of a circle, you can use the formula:
Area = (θ / 360) × π × r²
Where:
- θ is the angle of the sector in degrees
- r is the radius of the circle
In this case:
- r = 8 inches
- θ = 45 degrees
Now, plug these values into the formula:
Area = (45 / 360) × π × (8)²
Calculating step by step:
- Calculate (8)²:
- (8)² = 64
- Now plug this value into the formula:
- Area = (45 / 360) × π × 64
- Simplify (45 / 360):
- (45 / 360) = 1 / 8
Now the area becomes:
Area = (1 / 8) × π × 64
Calculate:
Area = 8π
So, the area of the sector is:
Area ≈ 25.13 square inches
Thus, we find that the area of the sector of a circle with a radius of 8 inches and an angle of 45 degrees is approximately 25.13 square inches.
