Question

from a rectangular metal sheet of sides 45cm and 48cm the largest possible circular sheet is cutoff .find the area of the remaining portions of the metal sheet

Answer 1

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

Find the radius:

Radius = Diameter ÷ 2

Radius = 45 ÷ 2 = 22.5 cm

Find the area of the sheet:

Area = Length x Breadth

Area = 45 x 48 = 2160 cm²

Find the area of the circle:

Area = πr²

Area = π(22.5)² = 1591.07 cm²

Find the area of the remaining portion:

Area = 2160 - 1591.07 = 568.93 cm²

Answer: 568.93 cm²
