If the circumference of a circular sheet is 66m. What is the radius of the circle

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\large\underline{\boxed{\bold\blue{Answer}}}$

$\green{Circumference \: of \: a \: cylinder = 2πr}$

$\large\orange{2πr = 66}$

$\orange{r = \dfrac{66 × π}{2}}$

$\orange{r = \dfrac{66 × 7}{2×22}}$

$\orange{r = \dfrac{462}{44}}$

$\large\orange{\boxed{r = 10.5}}$
