firstly r of the one circle be 14 and another be 7 cm
area of circle witd r 7cm=πrsq
22÷7×7×7 =154
area of circle with r 14 cm =πr sq.
22÷7×14×14=616
now,the space btwn the circle are
area of first circle -area of second circle
616-154=462cm
area of circle witd r 7cm=πrsq
22÷7×7×7 =154
area of circle with r 14 cm =πr sq.
22÷7×14×14=616
now,the space btwn the circle are
area of first circle -area of second circle
616-154=462cm

hiii!!!
here's ur answer...
area of circle(radius=14cm)=πr²
=22/7×14×14
=22×2×14
=616cm²
area of circle (radius=7cm)=πr²
=22/7×7×7
=22×7
=154cm²
area of space between the two circles=616-154
=462cm²
hope this helps...!
