Joanna bought three circular rugs to put in her bedroom. Each rug has a 4 ft radius. What is the area of her floor that will be covered by rugs? Round your answer to the nearest hundredth. Do NOT include units of measure in your answer.
The area of one circular rug can be calculated using the formula for the area of a circle:
Area = π(radius)^2
Area = π(4)^2
Area ≈ 50.27 square feet
Since Joanna bought three rugs, the total area covered by the rugs is:
Total area = 3 * 50.27
Total area ≈ 150.81
Therefore, the area of her floor that will be covered by rugs is approximately 150.81 square feet.
