1. A circle cutout is cut from a square of 28 cm . Calculate the area of the remaining paper?

To find the area of the remaining paper after a circle cutout is cut from a square of 28 cm, we need to calculate the area of the square and then subtract the area of the circle. Given: - Side length of the square = 28 cm 1. Calculate the area of the square: \[ \text{Area of square} = \text{side length} \times \text{side length} \] 2. Calculate the area of the circle: \[ \text{Area of circle} = \pi \times \text{radius}^2 \] 3. Subtract the area of the circle from the area of the square to find the area of the remaining paper: \[ \text{Area of remaining paper} = \text{Area of square} - \text{Area of circle} \] Let's calculate the area of the remaining paper. Calculate the value by following steps: - step0: Calculate: \(28\times 28-\pi \times 14^{2}\) - step1: Multiply the numbers: \(784-\pi \times 14^{2}\) - step2: Multiply the terms: \(784-196\pi \) The area of the remaining paper after a circle cutout is cut from a square of 28 cm is approximately 168.25 cm².
