Question

Circle O has a circumference of 367 cm
What is the length of the radius, /?
6 cm
18 cm
36 cm
72 cm

Answer 1

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

$C = \pi * 2r$

Where:

r: It is the radius of the circle

We have as data that:

$C = 367$

So:$367 = \pi * 2r$

We cleared the radio:

$r = \frac {367} {2 \pi}$

Taking $\pi = 3.14$:

$r = \frac {367} {6.28}\\r = 58.44$

The length of the radio is 58.44cm

Answer:

58.44cm
