Question

how many circular sheets of dia meter 20 cm can be cut out from a rectangular metal sheet of side measuring 157 cm and 60cm

Answer 1

Answer:

Step-by-step explanation...

Rectangular metal sheet sides  =  157 x 60

circular sheet diameter should be = 20 Cm

from width of metal sheet i.e 60 cm ..to get circular sheet with 20cm diameter we can only cut 3 circular sheets verticulerly (  60 / 20 = 3) = 3

As per length  157 of metal sheet ... to get circular sheet with 20cm diameter we can only cut 7 circular sheets horizontly (  157 / 20 = 7.8..) = 7

So total circular sheets = 3 x 7 = 21  ...

So we can cut 21 circular sheets from rectangular metal sheet ...
