A circle with a radius of 4.5 cm has a circumference of 28.27 cm
About 7 cm.
28 pi cm, about 88 cm
circumference = 2*pi*1.4 cm
If a circle has a circumference of 16 cm then the radius is about: 2.546 cm
Circumference = 2*pi*radius or pi*diameter Circumference = 87.9645943 or 88 cm to the nearest cm
circumference = 2 x π x radius ⇒ radius = circumference ÷ (2 x π) = 6.28 cm ÷ (2 x π) ≈ 1 cm
The circumference of a circle if the if the radius is 6 cm is: 37.7 cm
The circumference of a circle with an 8 cm radius is: 50.27 cm
If the circumference of a circle is 12 cm the radius is: 1.91 cm
A circle with a radius of 0.5 cm has a circumference of 3.14 cm.
A circle with a radius of 208 cm has a circumference of 1306.9 cm
