The constant of proportionality for this situation is 425
Step-by-step explanation:
When a quantity is inversely proportional with another quantity, then
the product of the two quantities is constant
1. If y is inversely proportional with x
2. Then y ∝
3. that mean y = where k is the constant of variation
4. Then xy = k
∵ In physics, Boyle’s law states that if the temperature is constant
∵ The pressure, P, of a gas is inversely proportional to the volume,
V, of the gas
∴ P ∝
∴ P =
∵ The pressure of the gas in a cylinder is equal to 250 kilo pascals
∵ The volume of the container is 1.7 cubic meters
- Substitute these values in the rule of variation to find k
∴ 250 =
- Multiply both sides by 1.7
∴ k = 425
The constant of proportionality for this situation is 425

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.
