Question
1. Find the area for circles
**Directions: Find the area for circles 1-4 and circumference for circles 5-8.** 1. A circle labeled with a radius of 12 meters. - Diagram: A circle with a line pointing from the center to the edge, labeled "12 m." 2. A circle labeled with a radius of 18 inches. - Diagram: A circle with a line pointing from the center to the edge, labeled "18 in." 3. (No circle or data shown) 4. (No circle or data shown) **Note:** For educational purposes, remember the formulas: - Area of a circle: \( A = \pi r^2 \) - Circumference of a circle: \( C = 2\pi r \) Where \( r \) is the radius of the circle. Please solve each circle problem using the appropriate formula based on the given radius.
