The question you're working on asks to find the area of a circle with a radius of 10 cm, using $\pi = 3.14$. The formula for the area of a circle is:

$A = \pi r^2$

Where:

• $r$ is the radius
• $\pi$ is approximately 3.14

Given that $r = 10$ cm, we can substitute this into the formula:

$A = 3.14 \times (10)^2 = 3.14 \times 100 = 314 \, \text{cm}^2$

Thus, the correct answer is 314 cm².

Do you have any other questions or would you like further details?

Here are 5 related questions to deepen your understanding:

1. How would the area change if the radius were doubled?
2. What is the circumference of this circle?
3. How would using a more precise value of $\pi$ (e.g., 3.14159) affect the answer?
4. How do you calculate the area of a sector of a circle?
5. What is the relationship between the radius and the diameter of a circle?

Tip: Always remember that the area grows proportionally to the square of the radius. So, even a small increase in radius results in a large increase in area!
