Question

If the circumference of a circle is 44 cm find its area

Answer 1

Answer:

154 square cm.

Step-by-step explanation:

Circumference of circle = $2\pi r$

Since we are given that the circumference of a circle is 44 cm

So,  $44=2\pi r$

$22=\pi r$

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

$7= r$

Area of circle = $\pi r^{2}$

                     = $\frac{22}{7} \times(7)^{2}$

                     = $154 cm^2$

Hence the area of circle is 154 square cm.

Answer 2

Answer:

=> The area is $154 cm^2$.

Step-by-step explanation:

Given that:-

The circumference of a circle is $44 cm$,

To find:- Area = ?

Let the length of the radius of the circle be $r cm.$

We know that,

Circumference of circle =$2\pi r$

Plug all the values, we get

$=> 44=2\times \frac{22}{7} \times r$

Simplifying it further,

=> $r = \frac{44\times 7}{44}$

=> $r = 7 cm$

For calculating the area we use the formula:

=> Area of circle = $\pi r^2$

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

                           = $154 cm^2$.

Hence, the area is $154 cm^2$.
