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`

`(32)/(\pi)=d`

`(32)/(3.14)=d`

`d\approx 10.19`

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