Step-by-step explanation:
Hello there, because you did not attached the photo or the information of the diameter of the circle, so I will solve this type of question under a general form
Let's assume d is the diameter of the circle
=> the perimeter of the circle is: dπ
=> the perimeter of the half arc of a circle
= 1/2 perimeter of the circle
= 1/2dπ
Hence, the perimeter of the stage shaped like a semi-circle:
= the perimeter of the half arc of a circle + the diameter
= 1/2dπ + d
= 3/2dπ
Just substitute d into the above expression, you will find out the answer.
Hope it will find you well.
Here the topic is "functions." Roughly speaking, we have a box. Input enters at one end and output exists at the other. Now, if every input value x (such as 2) is doubled by the box, every output value is 2x: (0,0), (1,2), (2,4), etc.
We call this "doubling" a "constant rate of change.
If you plot the points given, you'll see that they all are on a straight line. That straight line has the slope 2: y = 2x. Again, 2 is the "constant rate of change" here.
If you drive at a steady 55 mph, you are covering 55 miles during every hour behind the wheel. Again, 55 is a "constant rate of change."
