The answer depends on what the number 0.45 refers to: radius, diameter or area?
Area of a circle = pi*radius2
To the nearest hundredth, the circumference of a circle with a radius of 4 is 25.13
A circle with a radius of 5 units has a circumference of 31.42 units.
Radius of circle: 132/2pi = 21cm to the nearest integer
A circle with a radius of 4 units has a circumference of 25.13 units.
