Question

From a rectangular metal sheet of sides 45cm and 48cm, the largest possible circular sheet is cut off. Find the area of the remaining portion of the metal sheet.​

Answer 1

Answer:

2160

Step-by-step explanation:

45 x 48

Answer 2

Answer:

568.93 cm²

Step-by-step explanation:

largest possible diameter of the circle = shorter side of the sheet

largest possible diameter of the circle = 45 cm

Area of the rectangular sheet= length X breadth

= 45 X 48 = 2160²

Radius of the circle = Diameter ÷ 2

Radius = 45 ÷ 2 = 22.5 cm

Area of the circle =πr²

=  π(22.5)² = 1591.07 cm²

∴ Area of the remaining portion=

2160 - 1591.07

= 568.93 cm²

Answer is 568.93 cm²
