The diameter of a circle with a circumference of 18 is: 5.73
The formula for circumference is pi*d = circumference. Therefore just divide the circumference by pi to get diameter. Approx. answer = 5.73
18 x pi = 56.548
Circumference = pi*Diameter So D = C/pi = 40/pi = 12.732 inches (to 3 dp)
If a circle has a circumference of 8 the diameter is: about 2.546 (circumference divided by pi = diameter).
A basketball hoop is 18" in diameter and the formula for circumference is pi x 18" (3.1415 x 18"=56.54866")
It is 144.5 cm.
The diameter of a circle with a circumference of 18 is: 5.73
The circumference of a circle with a diameter of 18 yards is: 56.55 yards (diameter x Pi = circumference).
No it varied.
The circumference of a circle with a diameter of 18 inches is 56.5 inches.
The hoop is 18 inches / 457.2 mm in diameter.
18/pi
An 18" diameter circle has a circumference of about 56.5 inches.
56.548667764616276 circumference = PI * diameter
The diameter is about 18.
Circumference = pi*diameter So C = pi*18 = 56.5 units (approx).
