Explanation

To find the angle of the sector for cassava in a pie chart, we need to calculate the percentage of cassava compared to the total acres of all crops.The total acres of all crops is 2 + 5 + 3 + 11 + 9 = 30 acres.To find the angle of the sector for cassava in a pie chart, we need to calculate the percentage of cassava compared to the total acres of all crops.The total acres of all crops is 2 + 5 + 3 + 11 + 9 = 30 acres.The percentage of cassava is (3/30) * 100% = 10%.In a pie chart, the angle of a sector representing a certain percentage is calculated by multiplying the percentage by 360 degrees.Angle of the sector for cassava = 10% * 360 degrees = 0.1 * 360 degrees = 36 degrees.Therefore, the angle of the sector for cassava in the pie chart is 36 degrees.The percentage of cassava is (3/30) * 100% = 10%.In a pie chart, the angle of a sector representing a certain percentage is calculated by multiplying the percentage by 360 degrees.Angle of the sector for cassava = 10% * 360 degrees = 36 degrees.Therefore, the angle of the sector for cassava in the pie chart is 36 degrees.
