Question

find the diameter of a circle whose circumference is 44cm​

Answer 1

Answer:

14cm.

Step-by-step explanation:

Circumference of a circle = 2πr

2πr = 44

πr = 44/2

πr = 22

22/7 r =22

r= 22 ×7/22

r = 7

Diameter of a circle = 2r

               = 2 ×7

               = 14cm.

∴ Diameter of a circle = 14cm.

Answer 2

Answer:

The diameter of circle is $14 cm$

Step-by-step explanation:

In accordance with the information provided in the question,

Given the data in question  whose circumference is 44cm​

We have find the value of  diameter of a circle

We know that circumference of circle is $2\pi r$

Put the value of $\pi =\frac{22}{7}$

The circumference of circle is $2\pi r$

$2\pi r=44$

$\pi r=\frac{44}{2} \\\pi r=22$

Put the value of $\pi =\frac{22}{7}$

$\frac{22}{7} r=22$

$r=\frac{22\times7}{22} \\r=7cm$

So, diameter is 2r

$2\times 7\\14cm$

Hence the diameter of circle is $14 cm$
