Answer:
97.42 square units
Step-by-step explanation:
The area of a sector is given by ...
A = (1/2)r²θ
where r is the radius (12.2) and θ is the central angle in radians. Here, you're given the central angle as 75°, so you need to convert that to radians.
75° = (75°)×(π/180°) radians = (5/12)π radians
Then the area is ...
A = (1/2)(12.2²)(5π/12) = 744.2π/24 ≈ 97.42 . . . square units
__
Equivalently, you can find the area of the circle in the usual way:
A = πr² = π(12.2²) ≈ 467.59465
Then, multiply by the fraction of the circle that is shaded (75°/360°)
sector area = (467.59465)(75/360) = 94.42 . . . square units

7.0267
Step-by-step explanation:
The clue here is that the decimal point follows after the "and"
For example,
One and one thousandth = 1 + 1/1000 = 1.001
One and two hundred sixty-three thousandths = 1+ 263/1000 = 1.263
Hence;
seven and two hundred sixty-seven ten thousandths= 7+ 267/10000= 7.0267
