Question

form a square metal sheet of side 28cm a circular sheet is cut off find the radius of the largest possible circular sheet that can be cut also find the area of the remaining​

Answer 1

Answer:

Area of remaining sheet = 168 cm sq.

Step-by-step explanation:

Given side of metal sheet = 28cm

So, largest radius of the circle possible = 28/2 (As Radius 'r' = diameter/2)

                                                                  = 14cm

Area of remaining sheet = Area of square sheet  - Area of circular sheet

Area of square sheet = Side x Side = 28x28 = 784 cm sq.

Area of circle = πr² = 22/7 x 14 x 14 = 616 cm sq.

Therefore,

Area of remaining sheet = 784 - 616 cm sq. = 168 cm²
