Question

four equal circles are described about the four corners of a square so that each circle touches two of the other. find the area of the space enclosed between the circumference of the circle, each side of the square measuring 14 cm

Answer 1

area of circles=4pier^2

=4×22/7×35/10×35/10

=154cm^2

Area of square =a2

=14×14

=196cm^2

ar of square -ar of 4 circles =196-154

=42cm^2
