Question

The circumference of a circle is 32 cm which is the closest to the diameter

Answer 1

Given:

The circumference of a circle is 32 cm.

To find:

The diameter of the circle.

Solution:

We know that, circumference of a circle is

$C=2\pi r$

It can be written as

$C=\pi d$              $[\because d=2r]$

Where, r is the radius of the circle and d is the diameter of the circle.

The circumference of a circle is 32 cm.

$32=\pi d$

$\dfrac{32}{\pi}=d$

$\dfrac{32}{3.14}=d$

$d\approx 10.19$

Therefore, the diameter of the circle is about 10.19 cm.
