Question

Find the circumference of circle whose diameter is 49cm ,pi = 22 by 7

Answer 1

Answer:

The circumference of the circle is 154 cm.

Step-by-step explanation:

Given : Diameter of the circle = 49 cm and value of $\pi =\frac{22}{7}$

To find : The circumference of the circle.

Solution :

The circumference of the circle is given by $C=2\pi r$

or in the form of a diameter the circumference of the circle is $C=\pi d$

Now, we have given d=49 cm and  value of $\pi =\frac{22}{7}$

Substitute the value in the formula,

$C=\pi d$

$C=\frac{22}{7}\times 49$

$C=22\times 7$

$C=154 cm$

Therefore, The circumference of the circle is 154 cm.
