Find the area of the circle with radius 7cm

The area $A$ of a circle with radius $r$ is given by the formula:

$$A = \pi r^2$$

Given radius $r = 7 \text{ cm}$. We will use the approximation $\pi \approx \frac{22}{7}$.

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

$$A = \frac{22}{7} \times 49 \text{ cm}^2$$ $$A = 22 \times \frac{49}{7} \text{ cm}^2$$ $$A = 22 \times 7 \text{ cm}^2$$ $$A = 154 \text{ cm}^2$$

The area of the circle is $\text{154 cm}^2$.
