Question

From a rectangular metal sheet of size 20 cm by 30 cm, a circular sheet as big as possible is cut. Find the area of the remaining sheet.

Answer 1

Answer:the maximum radius of the circle is 20/2=10cm

So area of circle=3.14*10*10=314cm^2

Area of remaining sheet =600-314=286cm^2.

Answer 2

Answer:

Step-by-step explanation:

Rectangle

Length = 30cm

Breadth= 20 cm

Circle

Diameter= 20cm

Radius = 10cm

Area of rectangle = length × breadth

= 20 × 30

= 600 cm square

Area of circle = 22/7×10×10=2200/7=314.29cmsquare

Area of remaining sheet = area( rectangle) - area( circle) = 600-314.29=285.71cm square
