# How many circular sheets of diameter 20cm can be cut out from a rectangular metal sheet of size measuring 160 cm and 60 CM if the circles are placed as shown in the figure (take Pi 3.14)

dear student,

Area of the rectangular sheet = length * breadth
length = 160 cm
Area of the rectangular sheet = 160* 60 = 9600 cm2

Rea of the circular sheet = ${\mathrm{\pi r}}^{2}$
Diameter = 20 cm
Number of circular sheet obtained from rectangular sheet = $\frac{9600}{314}=30.57$
