Answer» (a) 5852m²(b) 44m²Step-by-step explanation:(a) Area of two CONCENTRIC circles = 2value of pie (R²-r²) = 2 22/7 (70²-63²) = {2 22/7(4900 - 3969)}m² = {2 22/7931}m² = {2 22133}m² = 5852m²(b) RADIUS of inner circle = 63 m So, CIRCUMFERENCE = {222/763}m² = 396 m² Radius of outer circle = 70 m So, circumference = {222/7*70}m² = 440m²Hence, Difference = 440m² - 396m² = 44m²
