How many circles, each with a 4-inch radius, can be cut from a rectangular sheet of
paper, measuring 16 inches x 24 inches?
(a) 6
(b) 7
(c) 8
(d) 12
(e) 24

A)6 
the radius is mentioned at four, meaning the length is 8
16/8=2 
24/8=3 
2*3=6 

Let us find the area of circle first

Area of circle = pi x r x r

= 3.14 x 4 x 4
= 50.24

Area of Rectangular sheet = 16 x 24
= 384

Thus, no. of circles = area of recatngle / area of circle

= 384 / 50.24

= 4.64

Thus, the answer is (A) , because it is the nearest.
