Question

Find the diameter of a circle whose circumference is 23.236km

Answer 1

Solution

Given :-

• Circumference of circle = 23.236 km

Find :-

• Diameter of circle

Explanation

Using Formula

★ Circumference of circle = 2πr

So, Keep value,

==> 23.236 = 2 * 22/7 * r

==> r = 23.236 * 7 /(2* 22)

==> r = 162.652/44

==> r = 1.696

Now, Calculate Diameter of circle

★ Diameter = 2 * Radius

So,

==> Diameter = 2 * 1.696

==> Diameter = 3.392

Hence

• Diameter of circle be = 3.392 kg

_______________

Answer 2

Step-by-step explanation:

Circumference of circle=23.236km

To find:

Diameter of circle:?

Formula:

Circumference of circle=2πr

Solution:

23.236=2×22/7×r

23.236×7/22×2=r

14.786=radius

diameter=r×2

Diameter=14.786×2

Diameter=29.572

Ans:Diameter of the circle is 29.572 km.
