Parking charges for first 2hours =$5 per hour after 2 hours parking charges = $2.50per hour
The formula for the circumference is 2πr.
The diameter d is given, which is 2 times the radius r (d = 2r)
So you have to calculate π d = 3.142×1.8 ≈ 5.7
Given the equation :

So, to find d , divide both sides by ( -6 )
So,

Note: when we divide two negative numbers, the result will be a positive number
Answer:
circumference of a circle = 2*pi*radius
just multiply 3.14 (pi) by 2 by the radius/diameter divided by 2
