Let's calculate each area. 4 m: We need to divide it by 2 to find the radius. 4÷2=2 Now let's put it in the formula. 2²π 4π=12.5663706≈13 6 m: We need to divide it by 2 for the radius. 6÷2=3 Now put it in the formula. 3²π 9π=28.2743≈28 Now subtract 13 from 28. 28-13=15 So, the difference between their area is 15 m².
