1.

The diameters of two circle are 8 cm and 12 cm respectively. find the ratio of the area of the smaller circle to that of the larger.​

Answer»

Solution:

here we find

                   1.    2r = 8cm

                           R = 4cm

          AREA=(4*22/7*16)cm2

                   2.   2R = 12CM

                           R = 6cm

          area=(4*22/7*36)cm2

so,the ratio of the area of two CIRCLES are

                   =4*22/7*16:4*22/7*36

                   =16:36

                   =4:9

Answer:ratio=4:9
