Answer:
50.24 yd^2
Step-by-step explanation:
The area of a circle can be found using:

First, we need to find the radius. We have the diameter. The diameter is twice the radius, or
d=2r
We know that the diameter is 8, so we can substitute 8 in for d
8=2r
Since we are trying to find r, we need to get r by itself. To do this, divide both sides by 2.
8/2=2r/2
4=r
Now we know the radius, and can substitute 4 in for r. Also, we can substitute 3.14 in for pi.

a=3.14*4^2
Solve the exponent
a=3.14*16
Multiply
a=50.24
The area is 50.24 yards^2

Answer:
-14
Step-by-step explanation:
You can find the amount of change by subtracting the original amount from the new amount.
11 - 25 = -14
Overall: Appropriate answer is, -14.
Ratio given 1:2
Let's suppose the ratio as x : 2x
Adding the ratio = 3x


40 and 80 are in the ratio 1:2 of 120.
