Circle has as circumference of 10cm, what is the radius

10/3.1416= diam
so 2r=D


r = 1.5915 cm (15.915 mm)

radius | 5/pi cm (centimeters)~~1.592 cm (centimeters)
diameter | 10/pi cm (centimeters)~~3.183 cm (centimeters)
area | 25/pi cm^2 (square centimeters)~~7.958 cm^2 (square centimeters)

go to wiki, type in circumfrence, get the equation, work it.
it's pretty simple

1.59

2*pi*r = 10

r = 10 / (2 * pi)

1.59

5

yes i agree, go to wiki.

5 cm? I think....
