Question

How many circles 54 cm in diameter can be drawn on a rectangular sheet of dimensions 1meter*2 meter? ( circles should not overlap each other)

Answer 1

area of circle
$= \frac{\pi}{4} (54 {)}^{2}$
area of rectangle = 100*200

divide both
$= \frac{100 \times 200}{ \frac{\pi}{4}(54 {)}^{2} } \\ \\ = 8.73$
since circle are reqd not to overlap.
hence 8 circles is answer
