Question

Two circles are drawn inside a big circle of diameter 24 cm. The
diameter of the two circles are
11
and
of the diameter of the big
3
circle as shown in the adjoining figure. Find the ratio of the areas of
the shaded part to the unshaded part of the circle.​

Answer 1

Step-by-step explanation:

he area of a big inside circle =pi x r^ square

d=1/2r

r=12

22/7*12*12= 452.16 area of big circle.

the diameters of small two circle 1/3 and 2/3 respectively

1/3+2/3=24

R=12

1/3*12= R1 =4

2/3*12 = R2=8

area of two small circle =pi(r2+r2)

22/7 (16+64)= 251.2

we need to find out shaded area = area of big circle - areas of two small circle

452.16-251.2= 200.96
