Question

find the area of circle where circumference is22cm​

Answer 1

Hey there!

Answer:

32.1536 cm²

Step-by-step explanation:

Given,

Circumference = 2πr

22 = 2πr

22  * 7 / 2 * 22 = r

7/2 = r

or, r = 3.5

Now,

We know,

Area = πr²

        = 3.14 * 3.5 * 3.5

        = 38.46 cm²

Hope it helps YoU!

Answer 2

$\bold{CIRCLE}$

Circle is a closed figure with no vertices.

Let the radius of circle be r then

Given,

Circumference is the distance along the side of a circle.

circumference = 22 cm

Since,

$\huge \boxed{Circumference = 2 \pi r}$

$\mathsf{22= 2 \times 3.14 \times r}$

$\mathsf{\frac{22}{6.28} = r}$

$\huge \boxed{r = 3.5 cm}$

Area is the number of square units contained in a enclosed circle.

$\huge \boxed{Area = \pi r^{2}}$

$\mathsf{Area = 3.14 \times 3.5^{2}}$

$\huge \boxed{Area = 38.46 cm^{2}}$
