Discover how to calculate the area of a circle with a diameter of 8 cm using a simple formula.

108 views

The area of a circle with a diameter of 8 cm can be found using the formula A = πr². First, find the radius (r), which is half the diameter: r = 8 cm / 2 = 4 cm. Then, calculate the area: A = π (4 cm)² ≈ 3.14 16 = 50.24 cm². Therefore, the area is approximately 50.24 cm².
