Answer:
about 41.9 square inches
Step-by-step explanation:
The area of a sector of radius r and central angle α is given by ...
A = (1/2)r^2·α
where α is in radians.
The angle 75° is equivalent to 75°·(π/180°) = 5π/12 radians, so the area is ...
A = (1/2)(8 in)^2·(5/12)·3.14 = (40/3)·3.14 in^2 = 41.86_6 in^2 ≈ 41.9 in^2

<em>Comment on the precision of the answer</em>
The use of a 3-significant-digit value for pi means that the answer must be rounded to 3 significant digits. If the 8-inch value for radius is really only accurate to ±1/2 inch, then the answer must be rounded to 1 significant digit: 40 in^2.
Answer:
23.9425 (Round if needed)
Step-by-step explanation:
This is 2 half circles so you can find the area of a circle and divide it by 2.
First circle has a diameter of 6 cm
6/2=3 cm
So, circle has radius of 3.
Area of circle= 3.14(pi) radius^2
3.14 x 3^2= 28.26
28.26/2=14.13 cm
Area of first half circle= 14.13
Repeat that process for the second circle.
3.14 x 2.5^2=19.625
19.625/2=9.8125
14.13+9.8215=23.9425
Area=23.9425
I’m not really sure if it correct, g(1)=0 or g(1)=1??
