From a circular sheet of radius 4 cm, a circle of radius 3 cm is removed. Find the area of the remaining sheet ( Take π = 3.14)

Radius of circular sheet (R) = 4 cm and
radius of removed circle (r) = 3 cm
Area of remaining sheet
= Area of circular sheet – Area of removed circle
= πR² – πr² = π(R²-r²)
= π(4² – 3²) = π(16-9)
= 3.14 x 7 = 21.98 cm²
Thus, the area of remaining sheet is 21.98 cm².
