Question

Find the diameter of a circle whose circumference is 23.2 36 km

Answer 1

Answer:

The diameter of the of the circle will be:

$7.39km$

Step-by-step explanation:

Given:

Circumference of the circle is 23.236 km.

Hence we have to find first the radius of the circle.

Formula used below has shown here:

Circumference of the circle $=2\pi r$

Here we can take the value of:

$(\pi=\dfrac{22}{7})$

Therefore it will become as:

$23.236=2\times \dfrac{22}{7}\times r\\r=\dfrac{23.236\times 7}{2\times 22}\\r=3.6966km$

Now we need to find the diameter of the circle and it can be find by using the formula:

$diameter=2\times radius\\diameter=2\times 3.6966\\diameter=7.39km$
