The two-digit number you are looking for is 12.
4 x 3 = 12.
6 x 2 = 12.
This fits your criteria.
Answer: C)46 ft
Step-by-step explanation:
We know that the circumference of a circle can be calculated with this formula:

Where "r" is the radius of the circle.
Since John is putting a fence around his garden that is shaped like a half circle and a rectangle, then we can find how much fencing he needs by making this addition:

Where "l" is the lenght of the rectangle and "w" is the width of the rectangle.
Since we know that the radius of the circle is half its diameter, we can find "r". This is:

Then, substituting values (and using
), we get:

90/300
To make it simpler, make it,out of 100 by dividing it all by 3. This will make it:
30/100
Therefore it is 30%
It would be B (530.7) because if you do 3.14 x 13 x 13 (Or to the second power) Then you get 530.66, the round to the nearest tenths
3 radical 70. 9 times 70 is 630, 9 squared is 3.
