Question

If Circumferences
of two circles is 462 and
308 cm, Find the ratio of their radius ?​

Answer 1

Answer:

Radius of first circle

R1

2πr1=462

πr1=231

r1=231/π

r1=231*7/22

r1=1617/22=73.5

Radius of second circle

R2

2πr2=308

πr2=154

r2=154/π

r2=154*7/22

r2=49

r1/r2=73.5/49

r1/r2=15/10=3/2
