Question

The circumference of a circle is 36.2 centimeters. What is the length of the diameter of the circle?

Answer 1

Given:

Circumference of the circle = 36.2 cm

Circumference of circle = 36.2

$\Rightarrow$ $2\mathrm{\pi r}$ = 36.2

$\Rightarrow$ $2\times \frac{22}{7}\times r=36.2$

$\Rightarrow$ $r=$$\frac{36.2\times 7}{2\times 22}$

$\Rightarrow$ $r=$$5.76$

Diameter of circle (d) = $2r$

Diameter of circle (d) = $2\times 5.76$

Diameter of circle (d) = $11.52$

Hence, The diameter of the circle is $11.52$ centimeters.
