if I have the circumference of a circle how do I find the diameter, and how do I find the radius

The formula for finding diameter is:

Circumference = pi * d

Therefore, insert your circumference, and divide by pi or 3.14 to get the diameter.

For radius:

Circumference = 2pi * r

So, insert your circumference and multiply pi by 2. Then divide the circumference by 2pi to get your radius.

Hope I helped! :-)
Diameter = Circumference/pi

Circumference divided by Pi = Diameter

Diameter divided by 2 = radius
circumference = 62.8 meters
using pi= 3.14

C = 62.8/ 3.14
= 20 meters

diameter =20 meters

d= 20 meters
r= 20/ 2
r=10 meters

thank you it was a great help
34yds find the circumference
34 yards for radius or the diameter?

cuz it could either be
(34x2) x 3.14= 213.52 yds
or
34 x 3.14= 106.76 yds

thats why you gotta state wether its diameter or radius
