A5cm x 11cm rectangle sits inside a circle with a radius of 12cm
what is the area of the shaded region? the shaded region is the circle - the rectangle inside it.

397.57

Step-by-step explanation:

Area of the rectangle                          = 5 x 11

                                                             = 55cm²

Area of the circle                                 = πr²

                                                             =   22/7 x 12 x 12

                                                             = 22 x 144/7

                                                             = 452.57cm²

Therefore , area of the shaded region

               = 452.57 - 55

               = 397.57cm²
