# If the diameter of the circle is 5 cm, what is the circumfrence and area of the figure?

Dec 26, 2015

The Circumference of the circle is $15.7 c m$ and Area is $19.625 c m$

#### Explanation:

We know that,

Circumference of Circle $= 2 \pi r$

and

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

The radius here is 2.5 cm because radius is the half of diameter. The value of $\pi$ is 3.14

Now,

Circumference of Circle:

$= 2 \cdot 3.14 \cdot 2.5$

$= 6.28 \cdot 2.5$

$= 15.7 c m$

Area of Circle:

$= 3.14 \cdot {\left(2.5\right)}^{2}$

$= 3.14 \cdot 6.25$

$= 19.625 c m$
