Question

find the radius of a circle with circumferene of 50cm

Answer 1

remember that circumference is
\[C = 2 \pi r\]
since you've got the circumference as 50cm, then you can find r by substituting the value to the equation and you'll have r as
\[r = \frac{ C }{ 2 \pi }\]

Answer 2

^

Just follow what @shinalcantara gave you.

\(r = \dfrac{C}{2 \pi}\)

Plug in the circumference and pi:

\(r = \dfrac{50}{2(3.14)}\)

Multiply:

\(r = \dfrac{50}{6.28}\)

Can you divide that? @ogolotswe
