Find thy radius.
Thy radius is 7.25 (D / 2 = R)
Thy formula for area is A = (pi)r^2
Substitute and Solve
A = (pi)r^2
= (pi)(7.25)^2
= (pi)(52.5625)
= 165.04625
Therefore, the area is about 165.
35% = 0.35
0.35*125=43.75=answer
Alternate way to find answer
1.25*35=43.75
Hello,
f(π/2)=4*sin(π/2)-2=4*1-2=2
f(0)=4*sin(0)-2=0-2=-2
rate=(2+2)/(π/2-0)=8/π
Answer D
You need to give us answer choices.
However, I looked back to previous questions posted on Brainly, and I found one that was similar to yours.

Answer:
We suppose that a is the old price in cents
the total cost of 9.20 $ equals 920 cents
so we have 20 liters bought with the old price (a) and 10 liters with the new price (a + 2). This is translated into this equation where a is the old price therefore our quest to be answered
20 xa + 10 x (a + 2) = 920 (cents)
20 xa + 10 xa + 20 = 920
30 xa + 20 = 920
30 xa = 920 - 20
30 xa = 900
a = 900: 30
a = 30 (cents)
therefore the old price for 1 liter of petrol is 30 cents
