# 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)

Area of the rectangular sheet = length * breadth

length = 160 cm

breadth = 60 cm

Area of the rectangular sheet = 160* 60 = 9600 cm

^{2}

Rea of the circular sheet = ${\mathrm{\pi r}}^{2}$

Diameter = 20 cm

radius = 10 cm

Area = $3.14\times 10\times 10=314c{m}^{2}$

Number of circular sheet obtained from rectangular sheet = $\frac{9600}{314}=30.57$

So, 30 circular sheeta can be obtained.
