circumference = 2πr
circumference of outer circle = 44m
44m = 2πR
44m = 2 x 22/7 x R
44m x 7/44 = R
radius of outer circle (R)= 7m
radius of inner circle (r) = R - width of path = 7 - 2 = 5m
area of path = area of outer circle - area of inner circle
= πR² - πr²
= 22/7 x 7² - 22/7 x 5²
= 154 - 78.6
= 75.4m²
