To find the area of the circle, we use the formula:

$\text{Area} = \pi \times r^2$

where:

• $\pi \approx 3.14$
• $r$ is the radius of the circle.

From the image, the radius $r$ is given as 4 cm.

Calculation:

$\text{Area} = 3.14 \times (4)^2$ $= 3.14 \times 16$ $= 50.24 \, \text{cm}^2$

Rounding to one decimal place, the area is:

$50.2 \, \text{cm}^2$

So, the correct answer is 50.2.

Here are 5 related questions to expand on this topic:

1. How would the area change if the radius was doubled?
2. What is the circumference of this circle using $\pi \approx 3.14$?
3. How is the formula for the area of a circle derived?
4. How would the area change if we used a more precise value for $\pi$, such as 3.14159?
5. What is the area if the diameter of the circle was given instead of the radius?

Tip: Always remember that the radius is half the diameter, so make sure you’re working with the correct value when calculating area or circumference.
