the area of the largest circle is 22/7*21*21=1386cm²

the area of the larger circle is 22/7*14*14=616cm²

the area of the smallest circle is 22/7*7=154cm²


now the area of the shaded region is {1386-(616+154)}cm²
=(1386-770)cm²
=616cm²


therefore the area of the shaded region of the largest circle is 616cm²
