We know that C=2 pi r and C= 10 pi
therefore 2r=10, r=5
Area, A=pi r ^2=78.54 square inches
We have been given an inequality 
. We are asked to choose the solutions of our inequality from given choices.
The solution of inequality are all values of x greater than 38.
Let us see our given choices one by one.
A. 
Since solution of inequality is greater than 38 and 25 is less than 38 , therefore, 25 is not a correct choice.
B. 
Since the solution of inequality is greater than 38 and 40 is greater than 38, therefore, 40 is the correct choice.
C. 
Since the solution of inequality is greater than 38 and 120 is greater than 38, therefore, 120 is the correct choice.
Hence and are solution for the given inequality.
The answer is B. 120/360 times the area of the circle
Let the weight of Paula's dog be x
Let the weight of Carla's dog be y
We know that the weight of Paula's dog is 3 times that of Carla's dog, therefore:
x = 3y ...........> equation I
We also know that the sum of the weights is 48 pounds, therefore:
x + y = 48 ............> equation II
Substitute with equation I in equation II:
3y + y = 48
4y = 48
y = 12 pouds
Substitute with the value of y in equation I:
x = 3(12) = 36 pounds
Based on the above calculations:
Paula's dog weighs 36 pounds
Carla's dog weighs 12 pounds
