Question: A circle is inscribed in a square with a side length of 8 cm. What is the area of the circle?

Options:

Correct Answer: 50.24 cm²

Solution:

Radius = side length / 2 = 8 / 2 = 4 cm. Area = πr² = π(4)² = 16π ≈ 50.24 cm².

A circle is inscribed in a square with a side length of 8 cm. What is the area of the circle?

A circle is inscribed in a square with a side length of 8 cm. What is the area of the circle?

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.
