Two circles length = 12cm Diameter of each circle= 6cm Formula for area of a circle is pie-radius-squared Radius of the circle is 1/2 of diameter=3 Formula pie-3squared= 9pie=area of one circle 9pie multiply by 2 = 18pie = area of 2 circles Now the area of the rectangle Formula is length multiply by width Length is 12cm Width is the diameter of the circle= 6cm 12 multiply by 6= 72 Now take the area of both circles from the area of the rectangle to find the shaded area 72cm squared - 18 pie (72-18pie)cm squared =15.5cm squared so the answer is the second option
