Question

(((I you know then give answer otherwise I will report you)) A square of side 80 cm, had patterns in circles of diameter 15 cm laid out each touching the other. Find the area of the square not covered by the circle

Answer 1

Answer:

6223.21 cm

Step-by-step explanation:

area of square =(side)square.

so,

80×80=6400cm

diameter =15

and , radius =15/2=7.5cm

pattern in circle =22/7 (we know that)

therefore,

remaining area = 6400 -22/7×7.5×7.5cm

6223.21cm
