Work out the area of a circle whose diameter is equal to 14 cm.

Lera25 [3.4K]

Given:

The diameter of the circle = 14 cm

To find:

The area of the circle.

Solution:

We have,

Diameter of the circle = 14 cm

We know that the radius of the circle is half of its diameter. So,

$r=\dfrac{14}{2}$

$r=7\text{ cm}$

The area of a circle is:

$A=\pi r^2$

Substituting $\pi=\dfrac{22}{7}, r=7$ in the above formula, we get

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

$A=22\times 7$

$A=154$

Therefore, the area of the circle is 154 square cm.
