Question

16 circles 16 semicircles and 4 quarters of radius 1 m are inside a square of side 10 m. How much area is left outside the circles but inside the square?

Answer 1

Answer:

• Area left=11.43 m²

Step-by-step explanation:

area of 1 circle= πr²

∴22/7*1²

=3.14

16circles+16 semicircles(8 circles)+4quater(1 circle)

=25 circles

∴area of 25 circles =25*3.14

=78.57

area of square =l*l

=10*10

=100

area left= 100-78.57

=11.43 m²
