Given that the dimensions of rectangular sheet is 1.57×4.16
So the area of rectangular sheet is 6.5312m2
Given that the radius of ice-cream cone is 2.5cm and the height is 6 cm
So, the slant area of ice-cream cone is πrl=51.05 cm2=0.0051m2
The number of ice-cream cones which can be made from rectangular sheet is 6.53120.0051=1280
Therefore, option B is correct
