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: 300x200
Step-by-step explanation: First of all...Your perimeter equals 2x+3y. X=length, y=width.
2x+3y=1200
3y=1200-2x
y=400-(2/3)x
y=400-(2/3)x
Your Area = xy=x(400-2x/3)=400x-2^2/3
dA/dx=400-4x/3=0
4x/3=400
4x=1200
x=300ft length
y=400-(2/3)(300)=200ft
I hope this helps you!
Answer:

Answer:
c(t) = 25 +12 * t
where t is the number of shirts
Step-by-step explanation:
The total cost for the shirts is the flat fee plus the cost per shirt times 150 shirts
total = fee + cost per shirt* shirts
1825 = 25 +c*150
where c is the cost per shirt
We need to determine the cost per shirt by subtracting 25 from each side
1825-25 = 150c
1800 =150c
Divide by 150 on each side
1800/150 =150c/150
12 =c
Each shirt costs 12 dollars
We want to make the function in terms of cost per shirt
c(t) = 25 +12 * t
where t is the number of shirts
