Acircle has a circumference of 32.4 mm. find the radius and the diameter. round your answers to two decimal places.

r=5.15

d=10.31

Step-by-step explanation:

Given:

circumference of circle=32.4 mm

radius=?

diameter=?

formula of circumference of circle is given as:

C=2πr

Putting value we get

32.4=2πr

r=32.4/2π

r=5.15

d=2r

d=2(5.15)

d=10.31 !

For this case we have that by definition, the circumference of a circle is given by:

Where:

d: It is the diameter of the circle

We have as data that:

Taking

We have:

The radius is given by:
