Answer:
B. 15 ft.
Step-by-step explanation:
We have been given that the circumference of a circle is 47.1 feet. We are asked to find the diameter of the circle.
We will use circumference of circle formula to solve our given problem.
Upon substituting the measure of circumference in formula, we will get,
Now, we will divide both sides of our equation by 3.14.
Therefore, the diameter of our given circle is 15 feet and option B is the correct choice.

According to the ratio of dogs to cats, if there are 20 cats, there will be 35 dogs.
<u>Explanation:</u>
Let the number of dogs be d and the number of cats be c
If the ratio of dogs to cats is 49:28, then the ratio of d : c would be
On reducing the fraction, we get
It is shown that the number of cats is reduced to 20.
So, let the number of dogs after sometime be x
Thus,
After cross multiplying we get:
140 = 4x
x = 35
According to the ratio of dogs to cats, if there are 20 cats, there will be 35 dogs.
