# 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)

**Solution:**

Radius of circular sheet (r₁) = 4 cm

Radius of removed circle (r₂) = 3 cm

Area of remaining sheet = Area of circular sheet – Area of removed circle = πr₁^{2} - πr₂^{2}

= π (r₁^{2} - r₂^{2})

= 3.14 (4^{2} - 3^{2}) cm^{2}

= 3.14 (16 - 9) cm^{2}

= 3.14 × 7 cm^{2}

= 21.98 cm^{2}

Thus, the area of the remaining sheet is 21.98 cm^{2}.
