The area = r^2 *pi
So it's 3.5 * 3.5 which is 12.25 pi
Answer:
- A → B: 1/3
- correct
- A → B: 2/5
Step-by-step explanation:
It is clear from your answer to the second part that you know the A→B scale factor is the reciprocal of the B→A scale factor. Use that fact for the other two parts of the question.
- A → B = 1/3; B → A = 3
- A → B = 2; B → A = 1/2
- A → B = 2/5; B → A = 5/2

It is convenient to find a unit length (or the smallest length) on the smaller figure, then see how much that is multiplied by to get the larger figure.
- B : A = 1 : 3
- A : B = 1 : 2
- B : A = 2 : 5
Once you have these ratios, you need to determine what the notation A→B is supposed to mean. Here, we presume it means B/A.

Answer:
C. 25/6 ft²
Step-by-step explanation:
Let's call the dimensions of Rectangle B x and y. Then ...
xy = 5 ft²
and
x² = 6 ft²
We want to find the value of y². Solving the first equation for y, then substituting for x², we have ...
y = (5 ft²)/x
y² = ((5 ft²)/x) = 25 ft⁴/x² = 25 ft⁴/(6 ft²)
y² = (25/6) ft² . . . . . . . matches choice C
20 + -14 = 6
