Answer: The area of the sector formed by central angle AOB is 5/8 th of the total area of the circle.
Step-by-step explanation:
Let r be the radius of the circle having the center O,
⇒ The area of the circle = 
square unit.
And, the central angle AOB = 
( since, 
= 180° )
Hence, the area of sector AOB
square unit.
Now,
⇒ Area of sector AOB = 5/8 × Area of the circle.
Hence, the area of the sector formed by central angle AOB is 5/8 th of the total area of the circle.
Answer:
The answer is c.
Step-by-step explanation:
12*12 = 144 so It would be 12
7*7= 49 therefore, it would be 7
C-d=b add to both sides d and will get
c-d+d=b+d
c=b+d
