Solution:

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 (r₁) = 4 cm

Radius of removed circle (r₂) = 3 cm

Area of remaining sheet = Area of circular sheet – Area of removed circle = πr₁2 - πr₂2

= π (r₁2 - r₂2)

= 3.14 (42 - 32) cm2

= 3.14 (16 - 9) cm2

= 3.14 × 7 cm2

= 21.98 cm2

Thus, the area of the remaining sheet is 21.98 cm2.

$\huge \boxed{\underline{\tt \purple{Answer ⤵}}}$

Radius of circular sheet (r₁) = 4 cm

Radius of removed circles (r₂) = 3 cm

of remaining sheet = Area of circular sheet – Area of removed circle = πr₁²

= π (r₁² - r₂²)

= 3.14 (4² - 3²) cm²

= 3.14 (16 - 9) cm²

= 3.14 × 7 cm²

= 21.98 cm²

• Thus, the area of the remaining sheet is 21.98 cm².
