Question

From a circular sheet of radius 7 m a circle of radius 2.1 cm is removed find the area of the remaining sheet

Answer 1

Answer:

Step-by-step explanation:

R = 7cm

r = 2.1 cm

Area of remaining sheet = area of entire sheet - area of removed sheet

                                        = πR²-πr²

                                        = π(R²-r²)

                                        = 22/7 (7²-2.1²)

                                        = 22/7 (44.59)

                                        = 140.14cm²

Hope this helps!
