Step-by-step explanation:

Radius of inner circle = 7m

Radius of outer circle = 8m

Area of outer circle = πr²

=> 22/7 x 8 x 8

=> 22/7 x 64

=> 1408/7m²

Area of inner circle = πr²

=> 22/7 x 7 x 7

=> 22 x 7

=> 154m²

Area enclosed between them = Area of outer circle - Area of inner circle

=> 1408/7 - 154

=> ( 1408 - 1078 ) / 7

=> 1330/7

=> 190m²
