divide the circumference (c) by pi (3.14) and then you have diameter. you will have to measure the radius by hand.
Radius: 45/2 = 22.5mm
C = D * pi = 45 * 3.14159(...) = 141.372 cm

The angular velocity of a wheel taking 45 seconds to rotate once is 2 2/3 pi radians per minute. The diameter of the wheel does not matter in this case.
If you mean 4/5 of 36 feet then it is 28.8 feet
The radius of a coin with diameter of 45 mm is : 45/2 = 22.5mm The circumference of a coin with diameter of 45 mm is 45*pi = 141,372mm rounded to 3 decimal places
divide it by 3.141592653 then divide it by 2
A circle with a radius of 45 units has a circumference of 282.74 units.
The diameter of a circle with a circumference of 45 cm is: about 14.32 cm
The circumference of a circle with a diameter of 45 inches is 141.37 inches.
Radius is 45.
If the circumference of a circle is 45 cm the length of the diameter in centimeters is: about 14.32 cm
32cm, the radius is half of the diameter
141.372 Circumference equals pi times the diameter: 45 x 3.1416 = 141.372 If you memorize the formula, it will serve you well.
Well, isn't that just a happy little question! To find the diameter of a cylinder when you know the circumference, you can use the formula: diameter = circumference / π. So, for a circumference of 45 centimeters, the diameter would be 45 / π ≈ 14.32 centimeters. Just remember, there are no mistakes, just happy little accidents in math!
A 45-meter diameter is equivalent to a circle with a radius of 22.5 meters.
An eighth of the area of the circle which, since neither its radius, diameter nor circumference are known, is an unknown quantity.
