Answer:
area of big circle = πr×r
=22/7×14×14
=22×2×14
=44×14
=616
area of small circle=22/7×7×7
=22×7
=154
area of space between two circles =616-154
=462

Answer:
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
