How

Many small circles of radius 7cm
can be got from big
big circle of radius
35cm​

Answer 1

Let get x as a number of small circles.

Area of big circle = Area of all small circles

(Here . implies multiplication)

22/7 . 35 cm .35cm = 22/7 . 7cm .7cm .x

x = (22/7 . 35 cm .35cm) / (22/7 . 7 cm .7cm)

x = (35 . 35) /(7.7)

x = 25
