Questions & Step-by-Step Solutions
A circle is inscribed in a square with a side length of 8 cm. What is the area of the circle?
Steps
Concepts
Step 1: Identify the side length of the square, which is given as 8 cm.
Step 2: Calculate the radius of the inscribed circle. The radius is half of the side length: 8 cm / 2 = 4 cm.
Step 3: Use the formula for the area of a circle, which is Area = πr².
Step 4: Substitute the radius into the formula: Area = π(4 cm)².
Step 5: Calculate (4 cm)², which is 16 cm².
Step 6: Multiply by π to find the area: Area = 16π cm².
Step 7: If needed, approximate the area using π ≈ 3.14: Area ≈ 16 * 3.14 = 50.24 cm².
Circle Area Calculation
– Understanding how to calculate the area of a circle using the formula A = πr², where r is the radius.
Relationship Between Square and Circle
– Recognizing that the diameter of the inscribed circle is equal to the side length of the square.
