Question

12. Two concentric circles have radil of 14 cm and 7 cm respectively. Find the area of space
between them.​

Answer 1

let smaller circle radius=7

bigger circle radius=14

now

area of bigger circle = πr×r

arae of bigger circle=22/7x14x14=616

area of smaller circle=πr×r

area of smaller circle=22/7x7x7=154

arae of space between them=area of bigger circle-area of smaller circle=616-154=462
