Henry constructed circle a with a radius of 10 units. He then created a sector as shown in the figure below. Which of the following expressions would help him find the area of the shaded sector?
You can find the area of sector by using the proportion Area of sector/ Area of circle = Central angle/ total angle of circle Area of sector = (Central angle/ total angle of circle) * Area of circle Area of sector = (θ/360)*(π(10)²) =(120/360)*(100π)
