Question

The circumference of a circle is 19.468 meters. Find the radius of the circle.

3.1 m
6.2 m
16.328 m
12.4 m

Answer 1

the circumference C of a circle is given by the subsequent formula:
\[\Large C = 2\pi R \cong 6.28R\]
where R is the radius of your circle

Answer 2

6.2

Answer 3

B.

Answer 4

if we divide both sides by 6.28, we get:
\[\Large R = \frac{C}{{6.28}} = \frac{{19.468}}{{6.28}} = ...?\]

Answer 5

3.1

Answer 6

correct!
