the radius of a circular sheet of metal is 14 cm a circular piece of the sheet is cut from it the radius of the remaining pieces 7 cm what is the area of the cut of piece .​

Answer 1

Hello

Area of the circle with radius 4 cm = πr² = π(4)² = 16 π cm²

Area of the circle with radius 3 cm which is removed = π(3)² = 9π cm²

Remaining area = 16π - 9π = 7π = 7 x 3.14 = 21.98 cm²

Hope This Helps You

Area of the circle with radius 4 cm = πr² = π(4)² = 16 π cm²

Area of the circle with radius 3 cm which is removed = π(3)² = 9π cm²

Remaining area = 16π - 9π = 7π = 7 x 3.14 = 21.98 cm²
