R = 7cm
r = 2.1 cm
Area of remaining sheet = area of entire sheet - area of removed sheet.
= πR²-πr²
= π(R²-r²)
= 22/7 (7²-2.1²)
= 22/7 (44.59)
= 140.14cm²
r = 2.1 cm
Area of remaining sheet = area of entire sheet - area of removed sheet.
= πR²-πr²
= π(R²-r²)
= 22/7 (7²-2.1²)
= 22/7 (44.59)
= 140.14cm²
