Question

From a circle raduis is 4cm,a circle of raduis 3cm is removed.find the area of remaining circle. (Take π3.14)

Answer 1

Answer:

21.98cm²

Step-by-step explanation:

R=4cm and r=3cm

Area of remaining circle= πR²-πr²

                                       =π(R²-r²)

                                       =3.14(4²-3²)

                                       =3.14(16-9)

                                       =3.14(7)

                                       =21.98cm²

Answer 2

Step-by-step explanation:

it is equal to the πx7 area is π4^2-π3^2
